Spend 800 Microsoft points on N+, a skillful action game with hundreds of levels jam-packed with switches, hazards and gold pieces. It looks simplistic, but the gameplay is filled with all kinds of strategy, from rebounding up walls to avoiding enemies. You can also create your own custom levels, although an option to share them via Xbox Live is sorely missing. The multiplayer options are sweet, too, but you'll probably spend more time with the single player game. N+ rocks.
