If you ask me, Gens V and VI have brought the perfect blend of classic design aesthetics, fun concepts, and not TOO SIMPLE like Gen 1. I'm not gonna sit here and claim Gen 1 didn't have it's fair share of epic and simple designs, but some are just... getting a little meh in retrospect for me.
Is Dragalge overdesigned? Seems cooler than Muk to me. MegaAlakazam>classic. Megablastoise overdesigned and not as good as classic. I could do this for days,but It's all relative and opinion, I hate anyone that sets up camp too concretely in any era.
