I will say up front that I really wanted to like this game. I played Gothic 2 and, though I found the game difficult, ended up enjoying it greatly. I anticipated Gothic 3 would be another open-world fantasy game with better graphics that would, like the prior game, rise above its flaws. I was mistaken in my anticipation. Unlike Gothic 2, which was greater than the sum of its parts, Gothic 3 is merely the sum of its parts, some good, many flawed.
The graphics are nice, but the animation is bizarre. The game writing and voice work is poor, resulting in real problems with immersion. The game doesn't telegraph well what you are supposed to be doing and how to interact with the world and the various items you'll pick up. These are all forgivable and leftovers from the previous game. Worst of all, however, is the combat mechanic. Gothic 2 was a little wonky in combat, but it all worked out. Gothic 3 does not work out. Combat is how you advance your character and interact with the world, and it is the most distancing and alienating part of the game.
Also, I didn't read well enough and picked up both Gothic 3 AND the Forsaken Gods Enhanced Edition. That was pointless. They're both pretty much the same game, with the latter being slightly upgraded. Thank goodness for massive sales. I would otherwise have been pretty angry.
If you like open-world fantasy games and have run out of entries from Bethesda, this game might be worth trying on a major sale, but chances are you'll end up disappointed. Sure, the lack of polish is annoying, but the actual gameplay mechanics themselves are just not there, leading, ultimately, to little desire to keep playing.
