I'm playing
Mercenaries 2: World in Flames (Xbox 360)
Mercs 2 has many shortcomings; dialogue repeats annoyingly fast, vehicle handling is twitchy, and missions aren't involving enough to really grip you.
I've Beaten
Lost Planet Colonies (Xbox 360)
Though it isn't compatible with the original game, Lost Planet Colonies is well worth seeking out for its refreshed online servers and distinct new play modes.
I Love
Battlefield: Bad Company (Xbox 360)

Left 4 Dead (Xbox 360)

An incredibly tense multiplayer experience like no other. A must buy for shooter fans.

Rock Band 2 (Xbox 360)
This refined entry replaces the original Rock Band as quite possibly the most fun-filled four person co-op game in creation. Just don't go looking for a huge evolutionary jump.
