You cant compare the 2. Witcher 2 had waaaay higher budget and was 100% story, while Two Worlds 2 was also about screwing around abit.
I kinda agree about Two worlds 2 having a shit story. It was your average kill evil king blablabla, dark magic blablabla, save woman in trouble etc typical kind of story. I loved the game thou, the crafting and item enchanting system was tons of fun, not to mention the atmosphere in the world felt soo alive. But yea......like I said, its not for everyone.
