I love Roll Playing, especially with d20 systems, Pathfinder being my current favorite. I prefer to 'get in character' and even try to speak that way, when possible. I don't like breaking the 4th wall too much. Immersive ftw! I prefer a mix of combat and diplomacy. It's awesome when we get to resolve things peacefully, but I also like cleaving things in half, so...
I do prefer to be up front with a 2h weapon dishing out justice, but I don't mind being flexible for the party.
