the only type of games available for the archos 604 wifi are javascript games that you can play using the built in Opera browser. just Google javascript games and a few will definitely pop up. they are usually simple like hang man and connect four. on the archofan forum there was some mentioning of two or three titles that were compatible with the archos, but i havent looked into it yet
No, buy a new one, the Archos 605 Wifi is rather nice!
