I bought it new--I still have the DC of the original W1 and the DC for W2 installed, oddly enough. I bought W1 upon it's release (long before the "Enhanced" build and then the DC) and had no idea what to expect--I loved the game for a while! I'd never played anything quite like it at the time. Geralt's fighting styles took me a bit to get used to, but it came fairly easy. The music, atmosphere, all of it was great at the time. But these days, as others have mentioned, it just doesn't quite play
An U5-engine remake will likely be something much different than the original. One trait I've always admired about CDPR is how they constantly keep building value and worth into their previously released software and IP. Several companies have followed suit since CDPR started their "Enhanced" and DC versions--when the rule before W1 was you make a game, you spend six months swatting bugs, and then you abandon it forever and move on. Gaming owes a lot to CDPR. I thought it was interesting, listening to a couple of the actual Witcher-series developers on the W3 Next Gen stream a couple of days ago, that they said getting back into Geralt was something they all pined for...;) Like the one dev said, "Geralt is the foundation of our company" (slightly paraphrased.) None of them were remotely tired of Geralt!
It is well known that I cannot err--and so, if you should happen across an error in anything I have written you can be absolutely sure that *I* did not write it!...;)
