If the original Thief game doesn't make the top 5 I'm going to have a hard time respecting any "best of" list released by Bit-Tech ever again. It literally gave rise to an entire genera of games (FPStealther). Everything about the game was refreshing and new at the time. And it's replay value, even today with the graphics being obviously dated, is among the best of any game I have ever played. Character development, plot, and story line were extremely well done. But the innovative and exquisite use of audio (for the time) was something that still holds its own. Christ, I bought an Altec Lansing ADA880R speaker setup just for this game my senior year of high school! Oh, also, @ Star*Dagger, you're thinking Vulcans. Romulans don't state facts, they're experts at subterfuge and misdirection. Hell, they practically invented trolling.
