>>21696546I only have the smash demo to compare it to.
The smash demo can be replayed over and over again while you discover how to play and counter fighters, and feels like there's always new strategies to discover.
The ORAS demo gives you a little fun for one round, then proceeds to be mindless island hopping for Steven's sacred Skitty or pathetic trainer battles. The cutscene rolling after every fucking adventure is horribly tedious to sit through.
