For all of you folk who enjoy using that other game slot on your DS, take note: Wal-Mart is having a sale on select titles. Whether you go with the option of picking up 2 games for $20, or 3 games for $25, it's a fairly decent deal, if we may say so.
To sweeten the deal even more, they're allowing you to choose from some compilation games, as well. Titles such as Risk, Battleship & Clue, and Centipede, Breakout & Warlords (!). So, if you're trying to bulk up your collection, you might want to head on over there and check out what titles they have on offer.
