Brygun:
There are few ways to help guide a match up.
"Mandalorian" has many meanings so perhaps to clarify:
1= the character from the recent series
2= A similiar character on their own journey
3= One of the people from Mandalore
Star Wars has a few game systems like the West End Games d6 from the 80s/90s and the d20 versions. Are you looking for one of those? house rules? free form?
Fair questions. I'm open to playing free form or with a system (save for the FFG system, don't care for it at all). I'd love to play my own Mandalorian with or without a group so solo play is fine as is a group campaign where I can explore my character's journey.
A squad of Mandalorians would be very interesting as would any era of Star Wars.
