yes, I agree with some people it would be cool for gym leader's to have a more characterish feel then just a battling robot who says the same stuff. Maybe more of a mission involved. Like for the first gym leader, you go there and he/she says "An evil, sinister looking person ran in and stole the decorations for my gym!"
And you have to go find them, then when it;s finally time to battle once you beat min/her, you get the badge etc. But when you rechallenge he/she says different things and may be doing something else.
And it'd be cool if you go to the gym at night, the traniers in the gym (excluding the leader) are asleep of something. But some nights they are awake!
