Sid Meier's Civilization Revolution (Xbox 360): Usually, when you hear about a Civilization game, you think of a grand, strategic undertaking, filled with managing resources, building cities, and taking your built-from-the-ground-up population through the ages... and all of that being done on a PC. Well, in Revolution you can skip the PC part and just play some good old Civ on a console. Pretty sweet right?
Dungeon Defenders (Xbox 360): It's a horde-based mish-mash of tower defense, third-person action, RPG leveling, and loot-grabbing insanity. All of these elements mix to create a hectic, yet strategic effort to defend giant magic crystals from being destroyed by waves of incoming enemy grunts and bosses. While it's definitely fun to set up your perfect defense alone, if you can manage to grab three other friends, you'll have a blast in co-op.
