As Raze and others have already pointed out, you still have a game in a perfectly playable state (which by the way won multiple GOTY awards - so it cannot be THAT bad and THAT buggy!). While it is disappointing that you cannot immediately play the EE edition, one day you will upgrade your system and you will be able to play the free EE edition.
As a sidenote: I was looking forward to Witcher 3 and even thought about pre-ordering it. However, having seen those whooping minimum req, I knew that I would probably have to wait a year or two before I could consider buying a computer which can handle it.
The problems with the game begin after Cyseal. I doubt video game reviewers ever get to the end of the game or even to the Braccus REX battle. They got to play too many games to even get half way though them all.
With all the testing, ACT 1 went out with very little problems. Luculla Forest and on was a disaster with the stinking glitches and atrocious combat balancing. We should have tested the entire game.
I've yet to finish it, always getting stuck in a glitch of some sort or find I'm wasting an excessive amount of time on a "puzzle" when the area I'm trying to get to is an uncompleted portion of the game.
Unless this Enhanced version is really going to be fantastic, I'm simply done as a Larian Customer. The 1st game was the only real good one they ever produced, and I feel like a fool waiting for something to come out that will be just as good or better.
