A lot of people complain about the design of the new Pokemon, and state the bad design as a reason why they won't be buying the games anymore.
If you look at the early generations, many of the Pokemon were based off of real animals and plants, and we could sort of relate to them. Then when we got to the 4th and 5th generations, Game Freak (I'm guessing here) ran out of feasible animals to base Pokemon on, and had to start making up new things.
We as consumers can't relate to these new designs, they seem ridiculous to us. But they only seem ridiculous because we can't really compare them to a real life animal. I feel that if Game Freak can make more realistic (to an extent) designs more people will like them, and buy more games.
Just felt like I should elaborate on my previous post a bit.
