Just finished gothic 3 a few days ago and I have to say I'm a bit dissapointed, it has it's ups and downs, great music and outdoors but, as has been said before it's just too much like oblivion in regards to joining all guilds, doing everything first time round.
They said you wouldn't be able to but you can :/
Also,you sometimes have to use marvin mode i.e. cheats or reload to your last save to finish certain parts of the game, nothing you can't get past but. . ., annoying. (spawn npc's e.t.c)
There are three different endings, well that's to say you can end it in three different ways, but the actual end sequences are quite similar, either you destroy adanos' artifacts, bring them to beliar and carry out his will or give them to innos and kill more orcs.
When you go back to their statues you'll be granted a vision into the future, which will vary slightly depending on what you decided to do.
Some pretty, modified pictures pop up too.
I enjoyed it but as with the other gothic games it got too easy. Better than oblivion but still no where near finished / what it could have been.
Oh and I reloaded about twice because of boars, once you use a spear or bow or magic or summon animal's yourself or charm them or just run, they are easy.
You can see that it was rushed at several points, npc's talk about things that you can't do, placeholder items, sometimes the main quest npc's are far too easy and die in one hit, doesn't seem like it was rebalanced.
Vast parts of land without any quests monster or scenery e.t.c.
Sorry, didn't have enough time to make it a short post.
