There is this pen-and-paper game called Ironsworn: Starforged.
It was designed to be primarily a solo RPG, so its system could be suitable as a complementary addition to your RPing on server (or even in SP?).
How to marry such a system of mechanics with a video game akin to FL is an open question,
but the main improvement that it could provide is to give guidance, ideas and risk/reward mechanics to you as a player who seeks to RP and lacks new things to try out. I am unable to properly test it now, but I will still leave it here for you to check out.
