siddham: Dont pay any attention to the OP.
Try the game yourself.
I did and I like it a lot.
I like it better than Oblivion for instance.
If you like open-world gameplay with an interesting plot to follow....TW is excellent.
If you like lots of different equipment and novel ways of improving it....TW is excellent.
If you like creating potions and traps and bombs etc to augment your character and playstyle....TW is excellent.
The voice acting is fine....it is just delivered in an odd style that takes a few mins to get used to; but once you do its fine.
The production values are not as high as Oblivion....so the critical types cant get past that....
But the gameplay is superior to Oblivion....IMO.
Also the version of Two Worlds available on GOG is bug-free.
I'm playing the first one now. Agree with pretty much all you said except the voice acting. While some is fairly decent, some of it is downright atrocious. Doesn't really bother me, but if you're the type that it does bother, you'll cringe a lot. Anyway, I'm having a blast with the game. Well worth the few bucks I picked it up for here.
