It's another two-release week on XBLA and the one I'm most excited about is Spyglass Board Games. For $5, you get Xbox versions of Checkers, Chess, Mancala, and Reversi (aka Othello). Each game can be played against the computer or online against other human players.
What a terrific addition to the XBLA lineup -- who can ignore a chance to get in some quick classic gaming online with friends new and old? And 4 games for five bucks. Great deal! Best of all, this is not likely to attract the Halo-crowd so playing online might actually be enjoyable for those who don't like to be cursed at, called racial epithets, or told are gay every 4.3 seconds.
