I am slowly gaining meaningful experience as regards to roleplay:
Most of my experience is with computer games (specifically hacknslash titles from Blizzard and Black Isle).
The list includes demos I've played just to get a feel of the game. Most of these (by virtue of the basically linear plot or limited scope of the demo) I've not played all the way through. I tend to get bored when there is no longer any mental puzzle to attack
Diablo - (almost completed) and Diablo Hellfire (3/4 complete)
Planescape: Torment - completed, loved it.
Diablo 2 and D2:LOD - through Act 1, looks simultaneously cool and unchallenging
Icewind Dale - almost completed
Baldur's Gate II: Shadows of Amn - completed
Dungeon Siege - almost got to the last fight before I got bored. The camera system is fun. The dynamic classing system interesting, but alot of the game content - spells and items - is obviously designed for the multiplayer gamer. I'm a solo play gamer, so knowing that there are lots of spells I may never learn to use us a bummer.
Adonthell: Waste's Edge (completed)
Arcanum - looks cool
Knights of the Old Republic - one day during a visit to Woodstock and Wereteddy
Vampire: Redemption - one night before I decided it was too dark
Avernum 3 - for about ten minutes
Of course, I am interested in the rest of the BG and IWD franchises, as well as the Jedi Knight franchise (more FPS than crpg, but still interesting)
As far as pnp roleplay, I've played one session of Dragonlance (the group broke up when the DM got a job in another city) and just joined a Star Wars pnp campaign.
As a sidenote, I don't consider games with a single starting point and linear plotting varied only by game style (Diablo?) to have much replay value. To have real replay value, a single start-point game would seem to need some mutually excluse side- or sub-quests, or even mutually exclusive main play paths."
