It's neat that you're so open about your self-criticism. Not sure I agree with all of it, though - but you made it so you probably have a better idea, heh.
I don't know why you would say Obs' games aren't fundamentally fun. Indeed, I would say that they *are* fundamentally fun, with some annoyances detracting from the overall experience. K2 had essentially the same gameplay as K1 except for some horrible balance issues... which you would probably only notice if you are a rules lawyer or as anal as myself. It doesn't have the tactical depth of TOEE, but I don't think that means the game isn't as fun... simply that combat is not the focus. It's debatable whether NWN2 is better gameplay-wise than NWN, so I don't understand that either. And in both games, characters are more memorable both visually and from a writing standpoint than Bioware's counterparts, especially in MotB. Care to elaborate?
Can't argue with the last point, at any rate. That's probably the single worst point in your games so far... it's good to see that at least you acknowledge this.
For one, it didn't have 3D graphics.
