I typically have the worst in-game behavior. I will attack characters, shoot my fellow players and often run astray from the main story line. I get lost for hours in the simple act of trying to shoot birds out of the sky with a sniper rifle or getting one of the games vehicles to do a barrel roll.
Granted I don’t have a sniper rifle or any vehicles (that I know of) in Baldur’s Gate, I was able to entertain myself for some time with the cows in Candlekeep.
Dinner is at my place; tonight we dine like kings.
