The plan, so we hear, is to release Xbox Live Arcade Unplugged as a budget title that will also carry a one month subscription to Xbox Live Gold. The hope is that this will prod buyers into subscribing to Live permanently.
The list of games includes:

• Geometry Wars Evolved
• Texas Hold 'Em Poker
• Bejeweled 2 Deluxe
• Outpost Kaloki X
• Wik: Fable of Souls
• Harwood Backgammon

Should be out this October for about thirty bucks or so.
