GameTap made me an offer that I simply couldn't refuse. Sam & Max: Season 1, Uru Live (this Christmas, if I don't get an invite to the Beta sooner), and over a dozen other games that I've wanted to play. Or play again. Coupled with a limited time offer of half-price, if I signed up for a year, made the deal too sweet.
From my initial impressions, it is going to be worth the money. I've only had a couple of hours with the service. Less with the games due to crowded internet tubes. So far the system is impressive. There are a couple of flaws, but the content seems to out-weight the frustration overhead.
Full reviews of GameTap, Sam & Max, and other games to follow soon.
