They could have made Gen IV ten times better. And if there are ever remakes or sequels I hope they do this
>Dialga gets an ability that creates trick room upon switching in
>Palkia gets an ability that induces gravity
>have gen V level pacing
>platinum's pokedex

I just can't understand why they didn't have those abilities in the first place. It would have been a good way to really introduce field effects.
