No. 33: Star Wars: Knights of the Old Republic II: The Sith Lords (PC, also on X-box)
Obsidian have a knack for making good sequels using someone elses' tech and world. This was a top quality sequel which in many aspects and features, improved on the original. Characters were well fleshed out and highly interesting with your character having a major influence on them to the point of turning them to the light or dark side. Unfortunately, it feels unfinished towards the end (well, it actually was unfinished), resulting it it landing at a reasonable 33rd place. Modders on the PC version have tried to restore the cut content, but I have yet to try these mods.
No. 32: Call of Duty (PC, now on PSN and X-Box Live)
The original, and some would say the best. IMO, the World War 2 genre would have died a lot sooner had it not been for this game. It cemented all the core elements that made the sequels as huge as they are. A solid single-player campaign told from 3 aspects (American, English & Russian), each with its own style and the core multiplayer CoD gameplay. Unlike most games at the time, it added a stealth element to the multiplayer making it all the more fun. When I think back to CoDs humble beginnings, I can't help but feel that some of the charm and passion present in this are now missing from the most recent iterations with fun but rather cheap gimmicks like Zombie mode.
