But like others above have recommended.. Pang, Bubble Bobble, Puzzle Bobble, Snow Bros series (and Joe & Mac Returns), Rainbow Islands are good ones for simple platforming fun.
Beware of New Zealand Story - it's harder than electrified acid coated nails!
Spinmaster / Top Hunter on MVS are also good colourful fun. Don't forget Bomberman too

PacMan or PacMania are great on vertical, as is Bomb Jack.
