I don't know about Costa Rica in particular, but things that seemed to spark my friend's interest initially were:

1) show them a few awesome trailers.

2) play an arena quest or two with them in 2-player mode. You can explain the controls and keep them from getting owned at first (which discourages them).

3) show them how a quest plays out against something cool-looking that you can fight well. Like a rathian. That can give them a better idea of what the game is actually like.

Good luck!
