One M-E roleplayer here.
I've been playing tabletop M-E RPGs since I was something like eight (or nine) years old, so for about ten years.
It's one of my dearest hobbies.
I've played in various games during these ten or so years - though in less than one could expect, it seems like I have a habit of engaging in never-ending campaigns that go on for years - and most of them have been set in Middle-Earth. Middle-Earth is quite perfect for a roleplaying setting for me: it's an intriguing and somewhat magical world which I know a lot about. I feel that in ME there's just the right amount of given information and open questions for a game master. Besides, random sentences or minor facts in Tolkien's work tend to inspire me.
As to other than tabletop RPGs, I've been playing in storytelling/written RPGs here in the 'downs for a couple of years now and I've always wanted to try larping. I used to play a computer RPG (Baldur's Gate II: Shadows of Amn) occasionally, but I never played it online with anyone, nor did I ever get very far in it.
