Well, I probably won't go any further with the series now (granted that I still haven't gotten the 3rd, 4th, and 5th generation games). I really can't stand 3D* camera - let alone cel-shading - for stuff like this, aside from the part where I have very little reason to get a 3DS anyway (hell, I still have yet to get my own DS Lite so that it's not completely painful to play GBA games as well as the few** DS games I actually do have). Maybe there'll be a fan remake that puts it into traditional 2D.
*I also don't like it for console games, but I've had to make my peace with that. It is one contributing factor as to why I don't play a lot of new games, though.
**read: three, with a fourth I ordered off Amazon yesterday.
The designs really don't bother me. There's bound to be some similarity with the sheer number of the things there are now.
