Nintendo wins it, and I would have said the same in 1999 (please note the consoles list goes as far as the Dreamcast which came out in 98) for one simple reason: Nintendo just has better games. Sega best point IMO was the Megadrive/Genesis and after that I can barely remember any of the games that came out on Saturn and Dreamcast and even with the Genesis a lot of the games on there you could also get on the SNES. The Dreamcast was a good system and ahead of its time but all of that doesn't mean much when you hardly have any games worth noting.
