The Wii has been slow to release many games, but incredibly busy at churning out Mario titles. Super Mario Galaxy 2 is Nintendo's fourth on the system, not counting Karts, Parties and other spin-offs (we count Super Paper Mario). Is it overkill? Well, not when the gameplay and platforming are this satisfying and addictive. In fact, it would be great if Nintendo turned around franchise sequels this quickly a little more often.
