I have seen them in passing but never picked any up. I loved the movies so I am not sure why I was really put off from the game but something about it just seemed a little odd to me. Maybe its due to always thinking of it as more of a movie??
My brothers and I were/are huge James Bond fans. We owned most of the games, on N64 and GameCube. My brother currently has Perfect Dark downloaded on his 360. However, I guess technically we don't have any 007 games on an Xbox console, even if Perfect Dark is a rip-off of GoldenEye.
I liked the classic movie series, thought the games were solid. While I liked GoldenEye, the thing that got me is that stealth was really never a big thing for a guy who is supposed to be a super spy. At the time I was all about being first person James Bond running through with his superior firearms ability, but when I got older and having playing Splinter Cell, Metal Gear Solid, and Hitman it was like...a little stealth would've been nice in the bulk of the games.
I liked the majority of the 007 games. There was an old Mission Impossible game that had a decent balance of action and spy stealth for that period. When it gets down to espionage games I tend to go with Splinter Cell, but the 007 games were decent in whatever genre they focused on with the FPS games being landmark.
I remember seeing a few of these games in commercials but I never really had the urge to go out and get them I just dont think that they were really worth the time or the money. The only 007 game that I could say that was really worth my time and my money was 007 Goldeneye. I don think that there is no 007 game that could beat that game I must say that that game was the most fun that I have ever had playing an James Bond game and I still think that it is the best that I have ever played in the 007 series of games.
