Welcome to the rpol family! We're an odd bunch, but friendly and fun, and we love helping new folks.
The FAQ section should answer a lot of your questions about this site, but please feel free to ask anything else you want to.
There are a few games in the systems you mentioned, plus many more you could try. fell free to check out the Wanted Players section to see what games are "hiring" at the moment, or you can make a post in Wanted GMs to request what you'd like to play.
