the wii was such a bad console it's cancer spread to the Xbox and PS3 and valuable talent had to spend time making motion control shovelware.
hell if you read between the lines microsoft decided that instead of releasing a new console, they'd release the kinect.
so the wii is the reason why we had to wait until 2013 to get new consoles.
thanks wii
Eh, I actually think the Wii was good. In a way. I mean the system itself sucked. The OS was terrible, the graphics were pretty shit but it did legit get a lot of good games. And honestly, I think it has the best control scheme out there for many games. If you're playing a game that legit doesn't need every button on a dual shock I much prefer the split nunchuck wiimote method. I wish everyone copied it. So much more comfortable than using a normal controller. That said, some games do need those extra buttons and I hate waggle for the sake of waggle, but for a game like Metroid Prime, oh yeah, pointer controls rock, Excite Truck was awesome.
But what it did to the market was bad as so many shit games were big sellers and everyone flocked to the casual gamer.
Now the N64, I do agree, I think it's the worst Nintendo console beside the Virtual Boy if that counts as a console.
The one thing I'd disagree with the OP on is Square and Final Fantasy. Sorry but Final Fantasy 7 never would have happened on a cartridge and never would have been the phenomenon it was on the Nintendo 64. Even if Nintendo money hatted Square and got them to stay I think they would've been nothing on the N64. The PS1 got so many great RPGs from them as well that objectively I think there's no real way for a consumer to say that company made the wrong choice as those games would have been shells of themselves on the N64, assuming they even went with those visions since they wouldn't have been feasible in the first place. Frankly, thank God Square split from Nintendo then.
