47. Serious Sam: The Second Encounter (2002)
Serious Sam is a light and tight homage to the weightier shooters of yesteryear like Quake and Doom. The main chracter's name is Sam Stone? What, was Max Granite already taken? Sounds more like an out of work pornstar from the Valley than a galactic protector. Still, the series was hugely successful and influential; spawning multiple sequels and an eventual release on Xbox Live Arcade.
