Based on the comic. I just finished downloading the game, or the demo, actually. The full game can be unlocked if one gives them $20. Once I've played it, I'll let you know how it is.
And this is still really funny. Read through the 04/09/05 strip for the full joke. I discovered this comic a couple days ago and I've read through 3+ years of it in the last couple days. Some of them are really funny. Most of them are at least pretty good.
