If you're interested in puzzle games, especially ones you can play with friends, I would highly recommend this game and others in it's series. The concept is simple, align four blobs of a matching color to pop them, and send garbage to your opponent's screen, but with a little thinking you can make large chains to really deal damage, and matches between players can get really intense in Fever mode. The cast of characters is also delightfully quirky, and no knowledge of Japanese is really required to enjoy the core of the game, but for those with some knowledge or access to a translator, the cutscenes and character info are interesting as well.
