Pokemon. my god. Easily, my 2nd favorite franchise of all time (zomg haloz 4tw lolcakes, jk) I've loved every game that comes out, they're really not bad, innovation has been pushed to the max, and black and white are totally awesome, but its the pokemon that get me.
Ever since Red and Blue, Pokemon has made giant leaps... but...eh...
I started with starters that look like this...

that turn into this...

and now the kids of today start with these...

that turn into these...

Yes, it appears that at least the evolutions are cool... but come on! I can't deal with these new designs... that three-headed dragon thing is the only Gen V pokemon I'd include in any tournament team of mine, and I'd be embaressed to bring anyone else!
Yes, we had the ugly Jinx's, Electabuzz's, and Magmar's, but we also had NidoKing, Rhydon, Charizard, Mewtwo, Dragonite, Aerodactyl, the list goes on!
Look, I like where the new games are headed, but I really just want better-looking pokemon. Johto? they knew what they were doing. Feraligatr didn't have an artillery piece on his back, but he was sure awesome.
Why can't we have another johto, a sequel with pokemon that are a majority cooler than the previous series? Don't give me that "Arceus is cool cuz he's the God of Pokemon" The concept of catching the Pokemon God was unheard of in the 90's, so why is it acceptable now?
(I'm going for more of a design than usefulness preference... although my second favorite pokemon, Gyarados, is a bit of a beast...)
