Roleplay and narrative give me meaning, where as rollplay and mechanics are important for tone.
When my decisions affect the worlds I play in I enjoy digging deep into worldbuilding with the other players and GM. When I'm stuck in railroaded combat in dungeon crawls I literally fall asleep.
I deeply love variety, from mundane combos to pushing the line of what is acceptable while still being grounded within the boundaries presented. You'll know I'm invested if I write pages of info.
