I played the demo, thought it was good, and bought it.
It starts to get really hard later on, as each scenario plays with the prestigefrom the earlier ones and you can't unlock later ones unless you ultra-smash earlier ones. (i.e. a brilliant victory on Stalingrad unlocks 2 more, but I only got a decisive). I'm on some impossible mission which I think I basically have to lose to continue (Baku), but I refuse to lose, so I'm not making any progress. I also don't have of that prestige resource, so I can't save myself
I might fail, then carry on with the loser missions. Then once I've done that RESTART it all and 100% brilliant victory everything.
(Terek, the one before, took me agggggges.)
I really like it, though. I like the "supply" business. Means it's all about encircling the buggers, starving them out, then attacking them. All as quickly as possible and whilst preventing them doing the same thing to you.
Also, put this game,
At the Gates on your radar. It's made by the guy who lead-designed Civ 5, and it's a list of reasons why Civ 5 sucked and ATG won't. It's going to have a map that gets snowy and has a supply mechanic like UOC.
