A few days back, the Tales of MI.net blog made the commendable effort to compile a fairly complete list of all Monkey Island fangames, past and present, legally suppressed and otherwise, download links included!
Most of these I've never heard of before, but I will say that I'm looking forward to playing Fate of Monkey Island 1 and 2 again. Relive some memories and remind yourself of why the reputation of the Monkey Island fanbase as being the best around is well-deserved.
