Take One More Turn in Civilization VI

We’re excited to celebrate the 25th anniversary of the Civilization franchise by announcing Sid Meier’s Civilization VI, the next entry in the award-winning turn-based strategy franchise. Be sure to follow the Steam Community group here and add the game to your Steam wishlist!

Sid Meier’s Civilization VI, set to launch on PC on October 21, 2016, offers new ways to interact with your world, expand your empire across the map, advance your culture and compete against history’s greatest leaders to build a civilization that will truly stand the test of time. Your story begins later this year!

Sid Meier’s Civilization VI includes:

  • EXPANSIVE EMPIRES: See the marvels of your empire spread across the map like never before. Each city spans multiple tiles so you can custom build your cities to take full advantage of the local terrain.
  • ACTIVE RESEARCH: Unlock boosts that speed your civilization’s progress through history. To advance more quickly, use your units to actively explore, develop your environment, and discover new cultures.
  • DYNAMIC DIPLOMACY: Interactions with other civilizations change over the course of the game, from primitive first interactions where conflict is a fact of life, to late game alliances and negotiations.
  • COMBINED ARMS: Expanding on the “one unit per tile” design, support units can now be embedded with other units, like anti-tank support with infantry, or a warrior with settlers. Similar units can also be combined to form powerful “Corps” units.
  • ENHANCED MULTIPLAYER: In addition to traditional multiplayer modes, cooperate and compete with your friends in a wide variety of situations all designed to be easily completed in a single session.
  • A CIV FOR ALL PLAYERS: Civilization VI provides veteran players new ways to build and tune their civilization for the greatest chance of success. New tutorial systems are designed to introduce new players to the underlying concepts of Civilization so they can easily get started on a path to victory.

This was a delightful re-entry for me into the Civilization Franchise. The game itself offers a wide variety of scenarios and other historical references that make the player feel like the ruler of the society. I bought this for a friend and we play it constantly. 10/10

Product received for free
I did not expect what I played. I am actually obsessed now.
At first - the game looks crappy and as soon as you begin to get into it, you learn more and more and end up being a master at the game within a few hours.

I am actually so glad I was given this game, thank you so much for making an awesome title.

F. I grew up playing this game on a disc copy, and when I saw it was on sale I couldn't resist. This game is EXTREMELY fun, and isn't too hard to pick up. I would choose this game over Civ 5 any day of the week, except wednesday, but this game and Civ 5 are completely different, yet exactly the same, if you know what I mean. The gameplay is very fun and can have you playing for days, or you could just be playing a game for a few hours and be done with it. The expansions are quite good but the possibilities in the base game are vast. Pick this game up for yourself, if you can't figure it out refund it and get Civ 5

Diary Entry 1- Heliopolis is under siege by Rome. I've been unable to send reinforcements because Caeser is moving his troops around my territory, destroying farms, mines and villages. I can't spread too thin in fear of my other cities being attacked.
So 5 handfuls of Heavy machine Gunners have been defending the city from catapult bombardments and grenadier attacks.
And now, he seems to have set his sights upon the neighbouring city of Memphis.

Diary Entry 2 - I've reached out to the Malinese and Isabella of Spain, and both have declared war on Ceaser. They are on the opposite side of him to me. So while they cannot directly help my cities, they will put pressure on the Western side. So hopefully I can repel the siege and push to his cities. I have a troop of tanks coming in from the Northeast, and a regiment of Marines coming in from the southeast.

Diary Entry 3 - The marine regiment was ambushed on both sides upon coming around a mountain. Despite the enemy taking heavy losses, we lost the regiment.
Luckily a reinforcement squad was detailed to memphis, so now it's a case of bunkering down for the incoming attack, and planning the counter offensive.
The tanks have made significant progress, taking the city of Ardea from the grasp of the Romans. They will continue their progress north, towards Rome itself.

Diary Entry 4 - A reserve regiment of Marines have rendezvoused with the tanks. The dispatch will push on to Rome, flanking from the south, whilst Memphis defends and draws the brunt of the Roman Empire.

Diary Entry 5 - We took two cities to the south. And i decided it was now the time to counter attack. Making losses along the way, we broke through the memphis siege, and took the city of Ostia. It was short lived however, as the enemy retaliated while we were at our weakest and reclaimed the city. Luckily, the reserve squad was just 1 click behind, so now we can retake the city again, and await reinforcements.
I see very little action on the Western side, I am beginning to believe my allies have hidden motives. Their troops linger on the enemies borders. Perhaps waiting until I am weak enough that they may strike both me and Julius Ceaser. I must prepare for this eventuality.

Diary Entry 6 - I was wrong to doubt Isabella. How could I let the seeds of battle cloud my mind. She commenced her march across the border today, and in one fell swoop, she liberated a city from the enemy. Her troops have now joined mine, and we march together to the heartland of Mother Rome-ia

Diary Entry 7 - Isabella and I, sat down today and signed the Permanent Alliance of our two peoples. We will forever be comrades in arms, and for this, I graciously gave her 3 cities as gifts. Not without proper thought mind you. They are in 3 strategic places to mine enemy and mine future enemies. This will allow us to adaquately aid each other in times of war, and even further each others growth.
To our future! -clinks glass-

Diary Entry 8 - Rome has fallen to Spain! I made a good choice in allies, Isabella is ruthless, a worthy opponent to any who may cross her.
The Chinese also declared war on Germany, Frederick reached to me.. unfortunately, as well as the war on the Romans is going, I cannot extend myself at this time. He seemed disappointed.

Diary Entry 9 - An achievement I am unsure of. We have created...The Atom Bomb. I don't know what to think about this. A weapon with destruction beyond any imagination. One that would win countless wars, but with such heavy costs. I must make sure this never falls into the hands of our enemies..

Diary Entry 10 - We were pushing the city of Cumae today, they had heavily fortified the city, and it seemed an arduous task. The combined might of myself and Spain, and yet we struggled.. A shadow appeared on the horizon. They came bearing the flag of Rome, and begun a charge on our flank. We were outnumbered, the rest of our forces had lagged behind to clear up the enemy remnants. We hastily mustered a defence as best we could. The doors to Cumae opened, the cities huge force came out to greet us. We were preparing for defeat..
But then there they came. The Malinese army! They routed the enemy on our flank. Taking advantage of this turn of tide, we charged the enemy city, gates wide open and with morale turned, we claimed it for our own.

Diary Entry 11 - It's been a long war, spanning many years. Due to the efforts of our 3 way alliance, we have chipped the Romans down to a fraction of the strength they once possesed. Brundisium is their final city, their last stain on a world so tainted by greed. I have the honour of being the one to remove that stain. I now make my march, our footsteps of doom bellowing down upon the city walls. We are coming..

Diary Entry 12 - As we approached the gates of the Palace, Ceaser panicked. He offered a Peace Treaty, along with all his coffers. "Why barter for what I can simply take?" I said, leaving a lifeless corpse on the floor. My troops rejoiced, sharing drinks with the Spanish, and food with the Malinese. What was I doing? I was looking across the border to the North... towards the prosperous Chinese Empire.

Honestly, you have to be a fan of these types of 4x games, to enjoy them. A lot of people find them boring because there's a decent amount of waiting around while you wait for buildings to finish, units to be trained, research to be finished etc. Saying that, I find Civ games to be faster paced than games such as Crusader Kings/Europa Unversalis. The learning curves are a lot smaller too!

You'll never find great graphics in these types of games, but you'll always find amazing gameplay, and that's what matters right? Great gameplay is what keeps you playing, not great graphics.
I'm not a fan of the newer games, Civilization: Beyond Earth especially. I think they completely ruined that game. However, if you enjoyed the previous games (1, 2, 3) or you want to get into the series without spending a lot of money. I whole heartedly recommend this game.

this was an amazing game. if you really want to see my hours if you look at my beyond the sword you will see over 2300 hours. i think what really made the game shine even more then it had was the mod community. i played the crap out of the ones i loved. one of my favorite was fallensword 2. it was so good that even made it into Beyond the sword expansion. so if you like that little taste download the actual mod.
