who else has indulged in this? once i got comfortable with the MT rules (basically the skills & task system) i just went "doctor who" on shit and allowed access to other systems as different dimensions or playgrounds.
folks had fun going from traveller to d&d to battletech to car wars, etc. of course the core settings got fucked up in the process, but since all had a good time it didn't matter. it was fun for them to do some crazy shit (like blow up the moon in the car wars universe) and then come back and see what had transpired. tested my ability to wing stuff, for sure.
has anyone else had the fun of doing this?
