I see. We just have different opinions on what RPGs should be and that's okay. I prefer a deep lake to a shallow ocean, so to say. I'll take bg3, disco Elysium or mass effect over Skyrim any day of the week.
I've still got 100+ hours in games like that as well.. they're just not as fun or memorable to me and I often end up bored before the end. Had to force myself to ignore a bunch of the map in order to finish Witcher 3 and kingdom come, for example.
Gothic 2 is like the sweet spot, imo. Large enough that you don't feel confined, but not that large that you get bored doing the same stuff over and over again. And while I did say that KC:D had me bored with exploration by the end, I didn't feel bad about skipping parts of it like I did in other games because there the size of the map is just for realism and it's not actually filled with meaningless stuff.
As for character building, I just play path of exile for that. I play RPGs for the stories. If it can have both, great, but I'm not gonna complain about build diversity in a game that I'm not gonna play more than once or twice anyway.
