Nintendo used to be good. I had a game boy classic, a colour, an advanced...and there I stopped. For consoles I had a NES, N64, Gamecube and then I stopped and went for an Xbox360 instead.
With the Wii and the DS the brand just started to go downwards imo. More and more they just started to turn out sequels and ports. Then came the gimmicks too like motion control, weird plastic versions of a steering wheel/golf club/gun/etc, then a new, different DS...and another one...AND another one (first, lite, dsi, dsixl) and now a 3ds which is also mostly just a gimmick.
Nintendo is still a huge company, but this crap, combined with not going international with AWESOME titles...yea, I quit getting nintendo things a while back. Apart from the DSi XL I got for my birthday, but that was a gift. And I still only have golden sun: dark dawn and FF4 for it (the games I got for my birthday as well)
