Nintendo is better by far, much bigger fanbase and alot more games. Sega only has one decent series, which is Sonic's. Nintendo has Mario, Zelda, Metroid, Star fox, Pokemon and Kirby for the big series. Then theres series starting off but already big such as Pikmin and Animal Crossing.
I still play my N64 which I got when I was in 3rd grade...
But when I got one of the first shipment of the DS Lite, I didn't think that in 2 years, the L and R buttons wouldn't work and the speakers would be dead.
Actually KHROME there was the Sega Genesis and the Sega saturn also. And nintendo is better cuz they have way more games and a huger fan base. Even if the games are childish they were classics that hugely influenced video games. If it wasn't for nintendo then the fall of video game biz would have continued most likely.
(Accidently tapped the enter key) finishing last post - It came out in Japan but when i said series starting off, i meant that not alot of people actually knew about the first one and it is getting more popular.
