"Hello, my name is Stefan and I am a cheater." "Hello Stefan!" /cheaters-anonymus.
To tell you the truth, I cheated right at the beginning of The Witcher 2 for the same reasons most of you already named. I, as a player, read all the books, but accepted Geralt's amnesia in the first game. In Witcher 2 though, after defeating the Salamandra, Azar Jarved and Jaques de Aldersberg AND recieving a legendary sword from a goddess, there was no excuse (in character) to start from scratch again. Not because of the time that went into maximizing Geralt's skills in Witcher 1, but the inconcistency. So I modded Aerondight to be extremely powerful, just as much as the Sihil from Mahakam and removed the vigor-aspect to be able to block any time I want and didn't have to roll around like Samus Aran. Still I spent almost 90 hours on the Witcher 2 (in my first playthrough out of 4; or rather 5 in a few weeks) and enjoyed every single second of it. It was no god mode, mind you - I still died now and then if I wasn't prepared - but when I was, I beheld the White Wolf of legend I knew from the books. That's far more important to me than gameplay mechanics.
And with Wild Hunt, I'll do exactly the same if I find a way to do so (and if Aerondight is importable x.x). Feel free to nail me to a tree, but I'll still take much longer to finish the game than most others. Walking instead of running, turning off every visual aid whatsoever (map, quest-markers, POIs etc.), no quicktravel... You name it. I understand the nerf from a design-standpoint, but The Witcher 3 will finally be THE Geralt-simulator I was waiting for since falling in love with this dirty, brutal world 8 years ago. And even while cheating, I can still enjoy and respect all the hard work that went into creating it while respecting Geralt's story and skills just as much. I'll still level up normally with nothing but a button in my pocket at the start of the game on Dark Mode, but not without my Aerondight. <3
