Well it gets a LOT better in the following games. I just finished Blood and Wine (second dlc for w3) and it was delicious.
Not sure right now if the choices I made lead to the scenes that transpired, but at least the illusion made me think that different events could have happened. Normal game, you get to the bad guy, have 0 choice but to kill him, see a cutscene after and watch the credits.
Witcher 3 not so much, things keep on going after you''d be sure they have ended. Ended the dlc (which in the timeline happens after the main campaign) on a high note, very pleased with the ending state of the character and company.
Now I guess I'm to play Tekken 7 until something else has my fancy. I also bought witcher 1 on steam (BECAUSE IM TOO LAZY TO INSTALL THE PHYSICAL COPY I HAVE), so maybe that, but I doubt it, lol.
*edit*
182 hours played, considering how many sidequests I have left, I believe this game is bigger than skyrim.
