Glad to hear I will not have much trouble converting my MRQ game to BRP.
There are things I like about MRQ and things I dont so will kit bash stuff from both to get what I want.

.
One question I have now that people have seen it for real is if I allow one player to play a sorcerer using the Mongoose rules and another a magician using the BRP rules will they be roughly balanced? I dont mind different magic systems but not if one is going to overpower the other.
