Welcome, [@TheCanadianJedi]! I also had to stop because of time restrictions, but I'm hoping to get back at it again, as well.
I enjoy basically all of those genres you listed off (not super polished on my Star Wars knowledge, though) except for the gangster/mob one. Haven't had any experience in that area, but I'm sure it has its merits, just like all the others.

The term we use here for "1v1" is "1x1" or "one on one" role playing. I find it can be even more enjoyable than group role plays for certain genres/plots. If you want to add me on skype, my name is [b]yoyohayli[/b].
