There are currently two games that have my interest the most.

A Boy and His Blob: I just can't get over how darn cute this game looks! The whole "hugging the blob" really pulls my heart strings! The game is single-player only, and has 80 levels to explore. You control a nameless boy and you advance by feeding a white blob jellybeans. The jellybeans transform the blob into various objects such as a trampoline that allow you to naviage the levels. It's a cross between a platformer game and apuzzle game.

New Super Mario Bros. Wii: I'm an obsessive Mario fanboy, what were you expecting? This is an ehanced sequel of the DS game New Super Mario Bros. It has more levels, more power-ups, and the ability for up to four players to play at once; a first for a Mario platformer. It's also the first sidescrolling Mario platformer to appear on a console since the SNES. I currently have this on my wishlist for a relative to give me as a Christmas present.

I'm nearing the end of Mario and Luigi: Bowser's Inside Story, and should have a review up soon.
