Dawn of War II
You have to appreciate Relic’s guts. In the original Dawn of War, it had a beautiful game, which generated three successful expansion packs, played nice in multiplayer, provided epic battles and was quickly enshrined in the Hall of Fame of RTS games. It had it all: base building, teching up, a lot of unit types, a lot of factions, an overall strategic map in the final releases, wargear for commanders, and scripted missions for the toughest challenges.
