I always prefer direct opinion of people I know a bit, less spoily and easier to extrapolate if it would be worth a try. So I'm gonna give it a chance, after Fallout 4 and MGS5 (and the tons of good other games I should do -_-).
I haven't looked for any english versions for my mods, but they are a must-have:
Community Patch (Should be 1.75 or something like that), Content Mod (2.6.1 or higher) and the Quest-Pack (4.2 or higher).
Then get some kind of program that lets you easily adjust the ini-file making it look way prettier and running more smoothly and you will have an excellent time.
Sadly i really cannot help you with my links because everything is in german.
Without those mods you shouldn't even bother installing it, sadly.
But you could start just playing 1 and 2(+addon) with some graphic enhancements first, because those games are very solid without mods.
Aaaand thx to replaying Gothic 3 now, i stopped completely with Fallout 4. I just raged way too much while building even simple things out in the open and the story never really sucked me in as i had hoped it would. Even exploring the vaults made me more excited about the lore than the actual mainquest.
