About This Game

Star Ruler 2 is a massive scale 4X/RTS set in space. Explore dozens, hundreds, or even thousands of systems in a galaxy of your choosing, expand across its planets, exploit the resources you find, and ultimately exterminate any who stand in your way. The fate of your empire depends on your ability to master the economy, field a military, influence galactic politics, and learn what you can about the universe.

Galactic Economy

Colonize planets, each with one of dozens of resources, working in unison to create bustling centers of production. The resources you choose matter, and will guide your empire and its conflicts throughout the entire game.

Custom Ships

Design ships that fit your needs, strategies, and tactics using our new 'blueprint painting' approach to ship design. Quickly and intuitively lay out the armor, weapons, engines, and internals of your vessels.

Politics with Power

Diplomacy and influence gathering are reinvented as a core mechanic of the game, giving meaningful alternative options to players and serving as a platform of interaction both between players and AIs as well as humans in multiplayer. Harness your influence to annex territory, spy on enemies, aid allies, and more! You truly have the opportunity to affect the political landscape.

Massive Scale

Running on our internally developed Starflare Engine, Star Ruler 2 is able to make full use of multi-core cpus, and runs on both 32 bit and 64 bit machines. The size of a galaxy is only limited by your hardware and ambitions!

Star Ruler 2 is a hybrid space 4X/RTS set in a fictional galaxy.

What is Great about this game:

- Intuitive and enjoyable fleet design, mechanics, and combat
- Nicely paced 4X/RTS that does not require twitch reflexes or ADHD to have fun
- High level of easy modification available and Steam Workshop support

What is Good about this game:

- Detailed ship builder allows for different ship designs as the game progresses
- Significant options such as diplomacy and trade to play the game as you would want to
- Good use of Steam features such as Workshop, trading cards, etc

What is Bad about this game:

- Frustrating initial difficulty that requires mods to become more reasonable
- Some systems such as the economy, resource dependency, and planetary development are too obtuse even after hours of play


If you can modify the game to relax its difficulty to a more manageable degree, Star Ruler 2 has a lot of good ideas to bring to the space 4X/RTS genre.

I'm going to make this short and sweet. I like the diplomacy part of the game, it's better with more participants. I have won matches without firing a shot just due to good diplomacy. The card system is perfect.

The tech tree is a mess. The developers may have had a logical flow in mind but whatever they were thinking I don't see it. The tech upgrades go all over the place and don't seem to fall in a logically linear order that we see in many other similar games.

The planet management portion is probably the biggest part of the game. Upgrades to make planets more capable require certain planet types. The level five planets require a huge chain of planets. Lose a planet at the bottom of the chain and a large portion of your chain of upgrades comes slowly crashing down, along with your income.

Fleet management is rather easy, the flag ship-support ship relationship is ingenious.

Ship design is an art form. Literally. It's like a mini-game in itself, just trying to get the most effective ship design with what tech you have, interior space and funding available. The more you design and test in battle the better you'll get. Note that the support ships can perform certain roles within the fleet, like protecting the flagship, killing the opposing flagship, etc. So you can design support ships to fit those roles.

The only thing i've not really figured out is the rate at which you gain anything other than money... influence, energy, FTL, etc.

Otherwise I like the game.

Star Ruler 2 is a gem of a game, this 4X game from the makers of Star Ruler 1 brings meaningful choices in a genre where most of your choices are dictated by trying to out do your enemies by sheer technological or military might. Instead here you don't have a tech tree with weapons and sub-systems coming out of the wazoo (While more veriety would be extremely welcome as in large battles you will just see a modern art piece with all the pretty colours and lines and such).

Flagships need support ships, this forms a fleet. The tech web makes use of links that provide improvements to pre-existing things. You must create a trade network to support your empire. This game has many good things about it that many just ignore because they are so acustomed to the typical stuff we know from other 4X Games, simplicity.

But here are the Pro's and Con's of this game in my honest and unbiased opinion.

*Deep and meaningful management of your colonies
*Beautiful space battles in their own right.
*Unique Race Options
*Fracking Ring Worlds and Planet Thrusters!
*Interesting take on the Tech Tree, making it more of a Web.
*Multiple methods of FTL, making for a unique way to play each time.

*Limited choice of Sub-Systems can make space battles a little stagnant and ship design a little pointless after a while, offering no adaptation to the enemy.
*Trade System can be a little too complex at times for some.
*No Empire Wide management options at the political level
*No Govenors to automatically manage worlds, a must have feature for anyone playing on larger maps or multi-galaxy ones.
*Sadly the FTL effect could use some changes, right now it is a little... too much. Some veriety would be nice for the others, less purple please.

Time for me to Plead to you!:-
Sadly, the Developer (At the time of making this review) has state they won't have the funds to remain operational by 2016. This means no SR3 or any further stuff for SR2. SR2 has A LOT of potential. As such it would be a massive shame to see Blindman Studio's close their door's.

This game is only £18.99 in the UK, I would say it's worth it, oh so worth it. Even if you feel it's too rough right now or dosn't have enough shiny things in it to be worth of your money, just buy it. Get stuck into the game and enjoy it.
This is not a AAA company making Star Ruler 2, they are just normal people who made two great games out of passion. Please consider either donating to them or just buying this, or even buying a copy for a friend, the multiplayer in this game can get really fun and intense when you go on a star killing bender!.

I am in no way affiliated with BMS. And I get nothing out of urging you to buy this game. Just look at the reviews yourself, this game has very positive feedback, some amazing mods and it can be yours for a pitence compared to a AAA alternative.

Awesome 4X.
It's simple and easy to get started with, with comfortable default configurations and designs to use.
As you play you learn the deep mechanics, allowing you to fine tune and personalize a lot of aspects to your tastes.
Many different races with unique playstyles

You play in a galaxy where everything can be used to get an edge over your opponents.

Battles are epic, with thousands and thousands of ships battling, you can use strategy to turn a battle around just by relocating your ships during the battle (skip drive), and redesigning your ships to exploit your opponent's designs weaknesses for the next battles.

You can also blow up the galaxy's black hole and watch the fireworks as more than half of the galaxy gets pulverized by the explosion

This is one of the best 4X grand strategy games money can buy. It is worth every cent. Great and easy modability, fantastic engine that should set the bar for RTS games in general and amazing multiplayer code. Not to mention the intuitive UI and all around customizability this game puts SOASE:Rebellion to shame for half the price.

TL;DR - Buy it.
