With today's announcement that a 'Dead Rising' demo is now available on Xbox Live Marketplace it really hit me that this summer has been the summer of Xbox Live. From 'LotR: Battle for Middle Earth II' to 'Saints Row' to 'Table Tennis', game demos offer hours upon hours of fun, and free, gameplay. Going beyond the demos, Xbox Live Arcade has been adding a new, high profile, game every Wednesday, like 'Frogger' and 'Street Fighter II'. These games are cheap and addictive, plus you can usually download a demo of them, as well. Finally, there have been several good expansion packs for games like 'PGR3' and 'GRAW'. Microsoft's strategy is quite savvy. During the summer gaming doldrums, offering new content and a slew of game demos is refreshing.
