This game has some interesting ideas in it that I've always wanted to see them return to, such as being able to select any world from the beginning. I s'pose due to the lack of colour, the world themes are more distinct (with enemies to match) than the usual fire-ice-desert stuff; this game did Mario in space long before Super Mario Galaxy! A counter for defeating enemies, though the reward is a little underwhelming.

Perhaps, though Bowser did eventually copy Wario's shtick of using Mario's powerups against him...!
