I'm really loving this generation, from the graphics to the little feature like bending down to kids when you speak to them etc.
The only and major disappointment for me is the severe lack of new Pokemon. I went into EB Games today to buy Pokemon Y thinking there's going to be a whole new brad range of Pokemon to choose from, when in fact there's just that little amount of new Pokemon. It's really getting on my nerves having to walk into a path of grass, hoping that you'll come across an amazing all-new Pokemon when instead you find a Psyduck or an Oddish for the umpteenth time. It's ridiculous.
If I want to play and use older generation Pokemon then I've got RBY, GSC, FRLG, RSE, HGSS, DPPt and B2W2 to do so. I was expecting an abundance of new Pokemon but instead I've gotten the same old Pokemon recycled into 3D and slapped with a Mega Evolution. And some of the new Pokemon I've encountered I've loved, but many I think are plain silly - a keychain Pokemon? Seriously?
Game Freak are losing their creative touch, and are starting to get lazy. One might argue "quality over quantity" but I'd rather 100 new Pokemon with a few diamonds in the rough than around 50 with about one or two Pokemon gems.
