It's hard to believe that the seemingly innocuous phrase, "having a ball," could be tinged with cruelty. You see, the life of a nondescript videogame ball is actually quite miserable, rife with surreal landscapes, tilting mazes and suspiciously long half-pipes that only lead to pointless goals. Sierra Online's graphically splendid Switchball only exacerbates this sad state of affairs, featuring a shiny sphere capable of changing its physical properties (to overcome puzzles!), but not its emotional state. If you spend 800 MS Points ($10) on it this Wednesday, consider how you'd feel if tears rolled down your cheek and up the back of your head.

Hitting Xbox Live Arcade on the same day is Word Puzzle, a game that primarily deals with the useful thingamabobs that made this sentence possible. For 800 MS Points, you'll receive "intricate 3D boards," Vision camera support and the chance to use "exploding word bombs." Those should give the stereotypical Halo crowd a head start, at least.
