Kirby Super Star
You surely remember Kirby, the little pink ball with super powers, who made the heyday of the Super Nintendo.
Released in 1996, this platform game (sometimes called "Kirby's Fun Pak" in Europe) has eight games in one and is certainly the most successful and exciting episode of the series.
Inflate your body to fly and swallow your enemies to steal their power.
The game also features a particularly fun 2 player co-op mode.
