One of Two Worlds' first major problems is that it was clearly designed for a PC and not a console. Though the visuals are pretty nice, if a little stiff, the interface is incredibly hard to see. Text is way to small, even on an HDTV, making it hard to read any of the text that pops up during the game. This is especially problematic when trying to read maps; especially given the world's massive size and sheer number of things to see in it.
Technical issues aside, Two Worlds looks pretty good. The game world is huge and shows a nice amount of variation while keeping everything unified. You never get a sense that you're stepping out of the game world into an area that doesn't belong - even when entering some of the game's more exotic locales. Enemy designs are pretty nice, if a bit generic and there's enough variety in NPCs that you don't see many clones. Animation is pretty stiff, though the framerate often takes a serious hit when the action really gets going.
The sound's vocal aspect is laughably bad, but not because of the quality of the actors, but the dialogue. The game is loaded with Old English words, which makes all of the dialogue sound like badly written Shakespeare mixed with old Errol Flynn movies. Voicework is all over the place; you'll get a large dose of flat deliveries balanced out with some cheesy delivery that makes even the more serious moments funny.
