The thing is...this is what's happened with virtually every single Bethesda game. The core game is lackluster in so many ways, banking on it's breadth of content rather than the actual quality of it, and I essentially have to fix it myself or wait for someone else to do it. And even all that isn't going to fix uninteresting characters and questing. New Vegas actually had writing that made me want to look past the inherent 'meh' of several parts of the core experience, but it also benefitted from being able to significantly improve upon what Fallout 3 established mechanically.
And after playing Witcher 3, my bar for these kinds of games are even higher.
Means I just get to wait for GotY/Ultimate edition again before buying it. I'm still interested just based on what the modding community could potentially do with it. It's just not going to be a first week purchase for me.
I really need to finish that game...
