I've been playing RPG's for over 30 years now, and prefer older, more rules-light types of games. I like many different genres; everything from fantasy, to sci-fi, to pulp adventure, horror, and the Old West. I enjoy both playing and GM'ing but, if forced to choose just one, I would choose to be a GM.
I don't play voice/video games- only text chat games- and only using the Roll20 chat. I've spent countless hours trying to get comfortable using a mike and, the fact of the matter is, I've come to realize that I simply hate trying to roleplay verbally with someone that I'm not actually sitting at the table with. Also, I just RP much better via written text.
