Gothic 3 requires Mods to be really good. Then it's just as good as 1 and 2. Heck, i even liked the add-on after modders took care of the biggest issues. But it still has story issues that just can't simply be modded away, those were my main complaints. I played through it just as often as the first 2, so yeah, it's a great game. I just hate that it took many years of modding to get it there.
One thing is out-fucking-standing as usual though: the soundtrack.
Ah whatevs, might as well watch the video for nostalgia reasons =D
Have you tried Arcania, btw?
