I kinda agree with Brandon on this one, his stance seems to reflect mine and reminds me of a video i saw a while ago. I thought it was made by the guys who do the webshow Hard4games.
And the title kinda describes my feelings. They don't blow me away like they used to. Maybe it has something to do with them, maybe with me. But when i look at their latest Mario games, new Smash Brothers or Zelda i don't think that they are much different that the ones i played around 10 years ago. That's not to say that they aren't good, like Crowbar Man said, and i totally agree with him on this, Nintendo still has some of the most polished and well crafted games out there. But for me, that simply doesn't warrant an automatic buy, be it games or systems. Alot of people tend to say that you shouldn't try to fix what isn't broken. And that's true.
I just wish they would change it up a bit more, or try some things that are more OUT there.
