The 3D, in my opinion, is a huge leap forward for all Pokemon games. But it doesn't mean it's good!
The 2D was awesome, fine, ignoring the stupid 3D we face today. After Pokemon Conquest (AWSM game) was made, they started to make more effortless games. Pokemon Rumble? Ugh, come ON! :c
But I suppose it's okay, after all, the battles look okay. And the towns... so I shouldn't complain.
