Super Mario Galaxy 2.5

Review
Super Mario 2.5 is the Prequel to Super Mario Galaxy 2.

It takes place before Super Mario Galaxy 1 and after Super Mario Galaxy 2. This game will be set in the Mushroom Kingdom, and you will be using Launch Stars to fly to different galaxies. You do not need to collect power stars or rescue Princess Peach in this game, but you need to rescue inprisoned Lumas in each galaxy.
