“You are terrifying and strange and beautiful. Something not everyone knows how to love.” - Warsan Shire
I like to play GURPS, D&D3.5 & Pathfinder, as well as D&D 5e.
I like to play more unusual type of characters when it comes to games. Be it Dragonborn, Elves as a race and maybe Bards or Sorcerers as a class (with a twist of Thef, Warlock or a class that combines well with another one if I want to multi class) when it comes to D&D games. Or something like a Furry with psionic and / or magic powers when it comes to GURPS.
The rules of the game / games would need to explained or refreshed if I haven played it for a time as well as house rules and interpretations of rules that you as a GM / DM (or GM's / DM's) are using.
Be it before, during or after a game. Preferably before character creation.
