It was [i]that[/i] bad, however the frame rate, character models, and voice acting will either make you laugh (at how ridiculous it is) or get really frustrated.
It has a variety of enemies and weapons. The inventory system and stacking system is also nice. The magic system is also really good and I heard it was one of the best things in the sequel (two worlds II).
Note: If you don't want to break your controller, then don't even try swimming. I don't care if you have to cross a 10 foot river, it will be faster if you go around. (This is of course until you decide to spend points in your swimming skill, which is a waste).
