I *loves * it! 
I thought I’d start doing some RPG gaming at home, so I asked my friends here at the SDMB what I should try: Oy!'s gaming thread
For anyone who followed that, you might be interested to know that I ended up getting two Baldur’s Gates, two Dungeon Sieges, and NeverWinter nights. I tried Baldur’s Gate I first, but had trouble manipulating my character properly, so I switched over to NeverWinter. I’ve been much more successful here, and am working on Chapter 1, enjoying it a great deal. Thank you VERY much for your help.
