Gran turismo 3: A spec outsold both Halo 1 and 2 ... I'm pretty sure that game had the biggest impact as far as exclusives go. 

I'm pretty sure what started the FPS craze was CALL OF DUTY which ALSO originated on PC's. 

LOL, no it didn't on top of that it was one of the most bundled PS2 games so its sales numbers are misleading.  The FPS shooter craze actually started with DOOM but when we are talking about consoles it started with Halo and got even bigger with Halo 2 since the first game didn't have a online mode.  GT3 had little to no impact on what is popular on the 360 and PS3 especially since the game was completely a offline experience.

Until you can prove that the majority of it's sales were bundled the jury is still out on that one. I'm pretty sure there were popular FPS's before Halo such as Golden Eye 007 for the N64. The FPS craze didn't get bigger with Halo 2, it specifically got bigger with call of duty 4. 

@Bold You missed the point. 

Call of Duty 4 would have never been as big as it got without Halo 2.  Halo 2 put online console FPS on the map but your too young to realize that.  As for GT3 more then 1/3 of its sales came through bundles especially in North America where you can find the not for resale marked used copy almost as easily as the retail version that has a bar code.  As for Golden Eye the only reason it was fairly popular on the N64 is because the N64 had a limited library of games and it was released pretty close to the consoles launch and never went out of print.

Xbox did better than Gamecube but by a small margin so ur wrong by saying it did alot better.

GoldenEye was the first big console FPS, it created the mold for the FPS "blockbuster" and carried the N64 basically by itself for almost a year.

That said, the OP's point has some merit. Traditionally speaking the game industry has not supported three consoles without one getting shunned, with the exception of last generation where you had the Wiimote craze.

Super NES - Genesis - Turbo Grafx 16 (Turbo Grafx 16 the odd man out)

Playstation - N64 - Saturn (Saturn the odd man out)

PS2 - XBox - GCN (GCN the odd man out, considering MS sold more as an unproven entrant and ending XBox production earlier, XB probably could have sold 30 million units or more otherwise)

Last generation was an abberation, this generation is simply a return to form

PS4 - XB1 - Wii U (Wii U is the odd man out).

People don't need three different gaming platforms to choose from. 2 is plenty of competetion, 3 generally results with one being a third wheel. 

Yes it would have ... Whether Halo 2 put online console FPS's on the map were irrelevant because online FPS's came from PC's. Do you have ANY sources or official PR statements from PD or Sony to back up your claim ? Such a poor attempt to discredit Golden Eye 007's sales. The fact that you refused to acknowledge the game on it's own merits just goes to show how lopsided you are. You refuse to accept the fact that the original xbox is a failure and now you can't even accept the fact that Halo wasn't revolutionary ? 

It did a lot better in the US and North America nothing on the Gamecube came even close to being as popular as Halo and Halo 2 in that region.  As far as I know Halo 2 is the first console game to get a midnight release in the US.

I had friends who had little to no interest in Mario or even Zelda anymore who bought an N64 just for marathon sessions of GoldenEye.

It was a pretty big deal. I remember playing the game for the first time, and even though I wasn't a really big fan of FPS, I remember playing the multiplayer and getting that feeling of "wow ... this is something special". I think even Miyamoto before the release of the game singled it out as being really good, which caught some people by surprise because it was a game that had like little to no hype. No one was talking about it.

Sadly though I think GoldenEye was also the last time Nintendo was that relevant with the teenager/college-age male audience. They've never been able to replicate its success (though they haven't really even tried ... Perfect Dark and then uh ... Geist). 

Your missing the point once again ... You keep forgetting the fact that xbox was just as big of a failure DESPITE getting scraps from america. 

The irony in saying that I'm the one too young and yet you keep refusing to face the simple truth.
