I'm installing it now so I may be gone for awhile.. Talking about the freeform nature of the game that's what I really love too. I even like the way you sometimes make up quests for yourself. Like trying to find a particular armor set or having to build up enough skill to beat a tough monster, etc. Now that's creating your own adventure!
I remember from Morrrowind, Speechcraft was one of my favourites. The added dialogue/persuading options you get make it a must for me a major skill.
And did anyone ever do the combo fly ring+boots of blinding speed+dispel majic ring so you could fly like superman around the land? I count that as a glitch.. you could dive bomb your enemy or just shoot him with arrows from the sky. I wonder if OB will have something similar. Like JsARCLIGHT said, I reckon they'll eliminate these 'sucker punches' this time around. After playing the game for so long, when I got to be a supersonic flying tank I lost interest.
And hopefully my Nvidia 6800 GT will cope. I read a few posts that NVIDIA cards can be a bit crashy.
