Nintendo is successful doing their own thing. I can't explain it, they are not my style so I do not pay much attention but I do admire them.
Too young to recall Sega as I was born in 88.
Sony is my fav. Before Nintendo came up with their "insane ideas" it was Sony that did this. I like Sony because they take big leaps in hardware and software. From having a CD player, then DVD player and even winning with Bluray. People laugh at 3DTV but I bet they were the same ones laughing at the Wii. I like Sony because they think outside of the box and truly deliver on ENTERTAINMENT.
Microsoft just seems to pile the most crap together by throwing money at devs and calling it a package.
