Yeah, Gothic is better than Risen.
But Risen was not buggy at all. Gothic is more buggy, but it is by far the better game.
You also need to know, this developer doesn't make games for american market. This are german games and they don't want to dump it down just because the americans would like that. Risen is a bit more casual than Gothic, but even a good game.

The graphics in Amnesia are also dated for a game from 2010. And as the dark side already said, it is totally irrelevant.
The devs also wanted an old-school style. This is a reason for the animations. They wanted!
It is not because they are not competant enough to make ultra real animations, it's their special style and people really like that.

But yeah, Risen is not so good as Gothic. Gothic was made more for a special niche.

How can anyone stand those shitty Gothic games? Ugh, the first one was bad enough that I wanted to kill puppies and actually eat authentic Asian food.

I already told you, it's NOT a game for american casuals.

This is why you don't like it. It's just made for a small group of decent people who understand art in games.
