30. Tom Clancy's Rainbow Six Vegas (2006)
Platform: Xbox 360
Even we were getting the stale taste of the Rainbow Six series off the roof of our mouth in the mid-aughts. The franchise was trending toward ignominy, with Critical Hour being so lowly regarded that developers canceled a port of the title to other consoles. Of course, that just means that it's time to go back to the drawing board, which Ubisoft did in releasing Vegas in 2006. The title returned to what made the series great, employing great stealth sequences amidst crossfire-heavy moments in what became a beloved multiplayer title.
