Terrible.
This game has choppy combat with characters that are almost not responsive. All the controls are complex and too half baked. I felt the graphics were not as great as they could have been and the story was almost nonexistent. The inventory and customization screens are confusing and way too cluttered to make any sense. It's almost as if it was created ten years ago.
There were many glitches in the game and it was basically a bad experience to play.
The game felt very limited since there were only certain spells to use, you could only basically chop and hack at enemies with a sword and the creatures were not well thought out.
I know there are a lot of others who like this game, but I really didn't. This may be that I like games that are a tad more simple and easier to get the hang of. Other fantasy RPG games I've played have had more interesting creatures, less of a learning curve, and a more enjoyable storyline. It's mostly in these things I had a problem with in Gothic 3.
