Ah, yes, the game is called Company of Heroes, and you can find a pirated version using torrents but you have a lot of work finding products key and crack and you will not be able to play online cause you will be banned with a fake product key, but I think it can be purchased, I haven't tried it, I used the first way:D, but when I get a faster PC I'll buy it, I really want to give it a try online:D
The game has two expansions: CoH Opposing Fronts and CoH Tales of Valor, and also other mods like: Europe at War, Eastern Front and others. In Company of Heroes original, you have one campaign "Invasion of Normandy", using the US army, in Opposing Fronts, you have two campaigns: "Liberation of Caen" using British army, and "Operation Market Garden" using Panzer Elite, in Tales of Valor you have three campaigns: "Causeway" using the US paratroopers, Able and Baker; "Falaise Pocket" using the Wehrmacht, and "Tiger Ace" using the "most fear" Tiger tank, crushing over 40 british tanks ONLY in the first mission.
Maybe you're interested of campaigns that's why i gave those details, but also Skimirsh mode is available, you can give it a google search about more details or go www.relic.com for more games from relic;)
It has maybe the best strategy games graphics I have ever seen and the best audio quality :p
And what is funny at this game, that some of the units say lots of jokes, and also when they are under fire they say some words that can describe that moment being underfire or pinned...very relistic game
You can check out some gameplays on Youtube about it
Sorry for posting this but is one of my favorites game besides H&D2, and I could not refrain
