I've done a lot of tabletop. Some DnD, some of the Dragon Age rpg, we've even put together our own Mass Effect rpg based on the DA one. That aside I've also done Skype rp, and I usually end up taking video game RPGs a bit too seriously haha.
My first taste was a laughably bad IM RP thing I did with a cousin and some mutual friends of ours. It was terrible, using canon characters from some anime. I then moved on to joining a huge D&D group and got pretty into it, until retiring.
I came to PC and have RP'd here since, though I admit I am one of those on and off kind of people. I did get back into D&D and now I am double dipping my RPing between text and live action. I would say each helps the other, but I still find my talents inconsistent.
