mostly i am a GM (herald level by Wotc) ... running 2 games a week in 4e. the overall style of the games i run are a delve .. with more action and combat then rp, we tend to have a sense of humor while playing and have fun with it. but when the HP's drop everyone gets serious.
i do enjoy playing some as well, i have played since the early 80's on most every edition of D&D. i have to say i prefer 4th ed over them all.
i have always been interested in warhammer 40k but have never found others that have an army or are willing to play it. plus not having a place in town it can be played at.
