Probably Sony.

If you were born without fingers, would you still be on the internet?

I love hypothetical questions.

 This

If Nintendo became a 3rd party developer, I would probably end up buying whoever got most of their games
If Nintendo as a company suddenly shut down for some reason, and stopped creating and selling games. I would consider all of its games abandonware, and go nuts with NES, SNES and N64 emulation untill the PS3 gets enough games and a low enough price for it to be worth it

I like the interactivity and accuracy of the wiimote controls. Never liked dual analog. If there was no Nintendo I'd only play on my PC and not much at that.

Um... I couldn't care less about the company.

I didn't get a Wii because it's Nintendo. I got it because it has great games I want to play.

So it stands to reason I'd get the system that also had great games I'd want to play.

well don't really have allegance to a company. i have allegance to games i like.

since i love many nintendo games i obvioulsy get their system.

So if no Nintendo, then depends on where their games would go. If the games dissapeared or were on both, then based off last gen would have been PS2, but this gen the 360 seems to be a better deal and has more games that appeal to me than the PS3 currently does

Edit:  maybe just finally get a new computer, and just play that.  My current comp can play pretty much all games except cryisis level, so haven't had too much push to need ot update cause could care less about that game

Well.. there are two ways of answering this, and it depends on what the question implies.. (i assume it means the latter though)

1. Nintendo didn't exist at all - No clue, gaming industry would be very different today, and probably none of the same brands would be the same brands.. (note, sony formed because nintendo rejected a partnership, microsoft joined because sony joined)

2. Nintendo quit at some point
a) but kept making games - whichever console gets their IPs, and PC of course
b) stopped making games - stick with PC, and go to friends homes to play the one off good games on other platforms, like i do now

PC. 'nuff said

I have no allegiance. I didn't get a Gamecube last gen.
