While you might already have Planet Puzzle League on your DS, that might not stop you from buying the DSiWare Puzzle League Express (1 player, 500 DSi Points). Hell, it won’t stop me. For five bucks, you get the game’s four single-player modes: Endless, Clear, Score Attack, and Vs. COM. Considering I don’t have any friends who want to face me in this game and I don’t like carrying carts around, Puzzle League Express is relevant to my interests.
