I would agree that there are a fair few people who were fans of Nintendo N64 era, and therefore were never on top until now and enjoying it.
For example, last Fri. I went to youth group thing, and we played Wii and N64, as of course most people wanted to play with the Wii, I went for the n64, because I knew I would get the chance to play (only 8 slots to play for like 20 people). And I really enjoyed Mario Tennis (although Wii Tennis is better :P), and Mario Cart (and according to many people there, the GC version was better), but neither of thse games are mentioned on these forums. However, Goldeneye is considered Godly or somin, but when I played it (a game which was my first an only (until last Fri) go on an N64), I didn't find it great at all. I would much prefer playing 007 Nightfire, with 4 people, 4 AI bots and explosives :D The came was just really hard to play, and the 1 analogue stick was horrible to use for an FPS. There were no complaints when we switched to Mario Cart, and only one person was any good at it. I would say that argueably we had more fun playing Mario Cart. Personally if anyone finds that game hugely better than something like Halo, Gears, R:FOM, etc. then I'm just gonna assume they're biased, and really love Nintendo games. I just don't get why that game was so great (as many people have claimed it to be). I'm not trying to really bash the game here, I just don't think it lived up to the Godly status it seems to have with a fair few people here.
PS. When I was there, one of the guys (who had an N64, and virtually all other major consoles (excluding PS3)) held up the Zelda: OOT cartridge and said it was really good. I have yet to play it, and so I will assume he was right.
But I agree there are more people who own the PS3 on these forums recently, however I would say there has been a similar amount of people who favor the Wii who have come to thse forums aswell. I also agree with LeroyBrown, that you can not own all 3 and be objective. (if there wasn't a space between "can" and "not", it would have a totally different meaning lol :P)
