Are the Gothic games like Morrowind or what? What's the closest thing to compare them to? I haven't played the Witcher.
From what I know The Witcher's gameplay isn't very similar to Gothic, anyway, only the whole setting and tone.
Gothic 2 is much more streamlined than Morrowind, less technical. There aren't so many skills, and you only upgrade them in big, noticable steps. The combat also was rather a minor point for me. At least in the beginning it could be a bit tactical, but all in all even though you fight much, it was never a main attraction. I'd argue that in terms of how you control your character Gothic 2 is even closer to an action adventure than an RPG, though actually "playing a role" is one of its strong points.
I really can't think of another good game to call "very similar to Gothic 2", apart from Gothic 1, and the developer's half-sequel half-remake of Gothic 2, Risen.
What's bad about 3? I've heard people say that it was buggy to the point of being broken, but the developers also claim that it's fixed by now, so I dunno.
As far as I know it was indeed terribly buggy in the beginning, but by now it should mostly be very stable. But, as I posted before, the gameplay in general is still said to be rather mediocre, and the main strong points are a nice world to look at and a fantastic musical score.
[edit]
Damn, I thought I wouldn't want to get the X-Com pack after all. Then I heard
this again. Gosh, this game is terribly atmospheric. Listening to this music, I can basically see the terrifyingly dark corn fields of the damn night-time crash site missions, and hear the clanky footsteps of my soldiers as they move out of the plane. And the damn alien shots suddenly coming from nowhere with a loud PEW.
I think I want to play this again..
