I've played tonnes of table top rpgs over the years: D&D, AD&D (1st and 2nd Ed only), Gamma World, Star Frontiers, Boot Hill, Heroes Unlimited, Macross, Villains & Vigilantes, Call of Cthulu, Runequest ... and more that I can't think of at the moment. (This is being typed pre-coffee PDT_008 )
These days I'm more into playing JRPGs for Playstation/XBOX and Warhammer 40,000.
Have you tried Neverwinter Nights? Or the one that started the D&D transition to PC, Baldurs Gate?. I've been playing Neverwinter for 7 years, haha! Addicted completely. Mind you I mainly play online on different servers.
Don't know if you ever found our persistent world for Neverwinter nights before we wound it up due to lack of personnel, but I led a project called The Legends of Ferhan, which I was very proud of! We used a MySQL database to make the entire world persistent, and also allow us to generate custom encounters at any location on the fly (which if you've used the NWN editor you'll realise is quite a feat!). Loads of maps, slightly less content to go in them, sadly, which is why we had to wind up the project as there simply weren't enough hours in the day for the two coders (me and dms) to do everything that had to be done. That and I really had to finish my PhD at the same time!
Still, it was brilliant fun to do, and by the time we had decided to wind it up, there was about 30 hours of gameplay to be had as a single character. We're now looking at creating a new mod for the Source engine, and we're thinking that it will have a fantasy theme, but be a faster-paced, FPS-styled game than NWN was.
Yes, I'm a geek. Not as much into D&D as perhaps I could have turned out, but that's probably because I like shoot-em-ups too much so got very heavily into the FPS clan scene during my undergrad days.
