SNES all the way.
Sure.
Nintendo has always focused on making family games, as for Sega, they have made games JUST for the money.
Where has it got them?
Don't fool yourself into thinking that Nintendo isn't only motivated by money. I don't think I need to remind anyone else here that a lot of long-time Nintendo customers feel rather betrayed of late because of Nintendo's tendency to go for the easy sell.
It got Nintendo to be the BIGGEST gaming company currently going.
It got Sega...nothing, seriously, they don't even make gaming systems anymore.
So, SNES is definitely the best.
As I understand it, Sega suffered because they struggled to find a strong competitor to match Nintendo's Mario. When they did find a winning formula, they deviated so much from that formula with each progressive installment that they dug themselves into a hole.
What does Sega have anymore? Sonic. what does Nintendo have? Mario, Zelda, Kirby, Starfox, Metroid and Donkey Kong.
See the difference?
The number of frachises a company has to its name has nothing to do with how well that company does. Remember, for a while, Sonic was the popular one of that bunch. I will concede the point that Sonic now sucks, if you were implying that. There's no denying that Nintendo has a lot of good franchises, but quantity != quality.
