Haha cool. It's funny cause some of the creators if MI did some work for POTC. barbossa is LeChuck? :p

This is good, I can see Barbossa and LeChuck teaming up like that to wreak vengeance on our heroes(I, too, notice the similarities between them). Like you, I also notice the disappointing lack of Monkey Island/Pirates of the Caribbean xover. - I found a Sparrow meets Guybrush fic a while ago.

You're not the first one to think of this. I noticed the similarities myself and, like you, have not played Escape. I just haven't figured out what to write about. And there's a fifth one coming, as well.
