The big problem is, that MMM is a german project (I am Austrian - Mozart-Freud-Schwarzenegger),
but there do some episodes exist in english; due momentarely the mainpage
http://www.maniac-mansion-mania.de is down for maintaince a couple of days.
If you have some friends who speak a relative good english, german or spanish,
maybe the autor of those episodes can help you to translate (I mean the humor),
and make the MMM-project popular in (South)Korea so you and your friends can
enjoy the episodes fully.
We've been trying to make MMM as much international as possible, but the
bigest problem is still that there are to few translators; special the nativ ones.
