Revolutionary games break the mould by doing something COMPLETELY new/different.
Goldeneye was revolutionary. PD was and always will be
evolutionary.
I'm not sure, but Half Life seems to be revolutionary, and Halo evolutionary.
Super Mario 64 was revolutionary, MArio Sunshine evolutionary.
I'm very skeptical about calling Metroid Prime revolutionary, in that it's not a shoot-at-millions-of-baddies-in-gun-warfare, but rather an adventure much like Zelda. So i'm not that sure.
Geist may be called revolutionary, since you dont just play one person, but as many, but we'll have to see how well it's executed.
Perfect Dark was waaaaay over-rated. The fact that it was a Rare game in the mould of Goldeneye and '10000 times better' just made people talk of it in god-like terms with deathly amounts of exclamation marks. N64 Gamer gave it the rediculous score of 101% cause not only was it a great game with a great story, by allowing you to choose whether you want to risk the 2 frames per second multiplayer (4 players with 12 bots each), you could, where Goldeneye simply restricted gameplay if the framerate wasn't gonna be high.
Stupid, but true.
I was very 'wtf' about the rest of the game when i realised the scientist you had to rescue in the first two missions
turned out to be a freakin computer that flies and talks in a ghey british accent. Rare's attempts at a hollywood blockbuster type game were stifled by Z-grade acting and plain crappy plot developments.
PD was good, but not great. If Goldeneye had voice acting and the graphics of today, then it would have been the gratest game of all time. The game could benefit from better frame rates - imagine how cool that would be in multiplayer
