I never really got into the original CoH. I thought at the time that it deviated from the established RTS formally too much (imagine my surprise when DoW2 came out...) and the really precise "this is needed to counter that and that is needed to counter that" stuff was just annoying. there were also way too many missions of the "These are your forces, and they're all you get. Now go attack Hitler's Third Legion with them!" variety.
It also had a just plain stupid final mission. "What's the ONE thing that really pisses RTS gamers off? Oh, it's when they have to fight in multiple areas of the map at once. Let's make a map where they have to do so in three (four?) different locations! GIGGLELULZ!"
So... not terribly excited about this one, but Relic makes good enough games that it always warrants to keep an eye on them.
