Lil' babby nerd that's been in this hobby since I was 12. Biggest thing for me are the people I get to meet and chat with both in and out of character!
In play I'm much more of an "improv theater" kind of guy, preferring to be let loose and start describing things in the world and acting out NPCs (with GM permission) in addition to responding in character as often as possible.
I'm also willing to try ANY system! Do have a slant against "crunchy" but hey I've probably already read and understand the docs before. My personal favorite though is Genesys/Star Wars FFG thanks to how expansive and loose the results can be far beyond a simple "pass/fail".
