First, I want to state that I am a Poke'mon fan and I have been since I was ten. I have games from each of the generations and I have dedicated many many hours to catching and raising those monsters. Heck, I even plan on getting the Gold and Silver remakes coming out this year.
HOWEVER, I have a major problem: there's going to be a FIFTH generation of Poke'mon. This means that there are going to be FAR too many in my opinion. How the hell can I catch them all when there are bajillions of them? It took me AGES just to catch the 200 something on my Ruby version and fill that Poke'dex.
Not only that, the Poke'mon designs have been taking a MAJOR downhill tumble. In my opinion, many of the fourth generation Poke'mon are downright STUPID! Honestly, the folks at Nintendo/Gamefreak are seriously scraping the bottom of the barrel for ideas. How many times can they make some reiteration of Rattata or Pidgey? I'm sure by now that all the Poke'mon have some evolution of some sort even if they really didn't need one. Honestly, does anyone really care enough about Lickitung to give it an evolution; a HORRENDOUS looking evolution at that? The designs of the Poke'mon are looking more and more like some Digimon that got beat with an ugly stick and then thrown off a cliff and trampled upon. I'm certain that the fifth generation won't even really look like Poke'mon anymore so much as just a bunch of generic anime style monsters you see on Tamagachi or something (no disrespect to Tamagachi, just tryin' to prove a point! xP).
I understand that I Poke'mon is one of Nintendo's major cash cows and they'll keep making Poke'mon games and such, but do they really need to add 100 more every generation? The original ones that are awesome are getting lost in a sea of crap! *tightly hugs Charizard* They don't need more, they need to make them better!
That is all.
