What system?
Setting/milieu?
Are you a player or the GM/DM?
Type of story (ready-made or written by your GM/DM)?
Heavy on role-playing or more combat oriented?
Does the system cripple or encourage you as a player/GM?
One-time sessions or long campaign-arc?
Playing face-to-face or some modern variant (Skype/OpenRPG/play-by-post)?
If you're a player: why did you create your character the way you did?
And most importantly: if you're a player, what's your characters name?

I'll start:
I'm DM:ing a Swords & Wizardry-game with only one player via Google Docs. The story is written by me, and the milieu is a crossing between The Wind in the Willows and "standard" fantasy/Rustfooty.
We're up to 8000 words now, and so far it's been more about role-playing than die rolling.
With such a rules-light system, I don't feel hindered by it, although at times it feels like we've could've just started playing without any system (since the rules are mostly absent).
