All of my games are available to everyone for free.
However, if you enjoyed any of my games, a couple of bucks to cover website hosting costs and support my ongoing efforts would be gratefully appreciated. I think $2 per game enjoyed is a fair price. Thanks.

I guess so, though I have finished Curse of Monkey Island at least once (possibly twice or more) on each difficulty level. I sold my entire set of MI games to a mate, and thanks to Steam I'm probably going to buy them all back!
Never finished Escape from Monkey Island though, I hate that game passionately.
