L4D2 expands upon the already strong foundation created by its predecessor, by adding new infected and "power ups", along with the ability to revive fallen players. It continues to uphold the strong squad based and coordinated play I've come to love from valve games. Making it one of my favorites.

Fallout: New Vegas combines what Fallout 3 did for the series with the grit and grime that you found in the classic versions. Rather than roaming around a gray-green wasteland you find yourself immersed in the vast desert that is Nevada having to literally fend for yourself. This game is a must buy for anyone who is a fan of Fallout. The quests play better, the world is prettier and more expansive, more weapons, simplified skill trees, better karma, and way too much other stuff. Other than the vast amounts of bugs and graphical glitches it's a 10/10. Because it's got spurs that jingle jangle.
