As a player, I prefer the "harder" and/or "support" characters, such as the bard & cleric. I like to play by the rules -- some homebrew is OK, but weird crap that allows players to have 100 AC and do 50000 points of damage makes things meaningless, so exclude me from that junk.
I think games that are 3 or 4 hours are too short, and games that are 8+ hours are too long. I'm in my early 40s, so playing with people who are in their 40s or 30s feels right.
Currently in a Kingmaker game. Very fun so far. I play a druid -- I heard that Pathfinder nerfed druids/polymorph a little, so it seemed like a fun challenge to make a viable, capable character out of that.
