Some moves and abilities don't translate so well into actual RP, and logistics behind moves may not be so fun to follow by the book in RP. So for instance allowing creative use of moves.

And then there's the matter of having moves in general, which in game were designed to be learned progressively to suit the level group. What do we do here? Do we just get to choose 4 out of their entire learnable moveset? Or do we have to choose low levels, and if then how do they learn stronger moves? And then there's limit, we can keep to 4 sure, but there are just so many moves.
