Early review -
I've been a wargamer for a long long time, so I perhaps have a bias towards games like this. This is a grand operational level game where you control one of the two alliances in WW1, with a choice of 5 start dates. It's a bit like Panzer General etc. in that it's turn based - you move and attack with all your units one at a time, then your opponent takes his turn and does the same. It's not
like PG in that it is one continuous campaign - no linked scenarios with core units gaining xp, Also, you have to control both land and naval units, as well as manage research and unit production. There is multiplayer, but I haven't tried it so far, and there is only AI for your opponent (you're thrown in the deep end - you have to manage everything for your side yourself).
I suggest you check out some of the let's plays by RiotHouseLP if you want to see what the gameplay is like. One thing about those LP's though - they're a year old, and it looks like the game has had one or more updates since then.
The AI is reasonably competent - on land it knows how to break through weak spots in your line and encircle and cut off units. My advice on either side of the 1914 start is focus on cranking out cheap garrison units until you have enough to maintain continuous fronts with some reserves. The AI wasn't so good with the German Navy though - when I loaded up my first BEF units to cross the channel, it sent a battleship and cruiser into the channel to attack a transport. This might have been ok if he was certain to sink it, but he didn't, and anyway I don't think it's worth sacrificing a battleship just to kill one land unit. So the AI doesn't know the value to the Germans of just keeping a fleet in being. It seemed to handle the Allied fleets better.
OK, back to my 5th start - maybe this time I can make it through the end of 1914 at least ;)
After another couple tries starting as CP in 1914, I've given up for now trying to win with them until I get better at the game. One of the things I like most about historical wargames is when by playing them you can learn a real historical lesson. In this case, the lesson is that the Central Powers have almost no chance of winning if they can't knock out at least one of their 3 opponents in the first year. After that, the numbers are all on the side of the Entente for winning any war of attrition.
I've now played a complete game as the Entente. I won through to a complete victory in 1917. I defeated Germany and Austria-Hungary early in 1916, but the pesky Ottomans wouldn't surrender until I moved some armies all the way across the map to Egypt and the Caucasus to start putting a hurt on them. It was worthwhile though because learned how to perform an amphibious invasion and I got to see the importance of massed airpower, artillery, and shore bombardment in punching through otherwise hopelessly strong static trench defenses.
So, a definite thumbs up!
