I own both games on GOG, btw. They are treated as separate games.
To the guy with Vista...man, I suggest you update soon because you are already missing the game compatibility boat. But, maybe this game is one of, say, the two or three games you own?
I'm not one to let himself being 'pushed' (there is really no other way to describe it) into buying 'new' stuff without a reason. A reason that isn't invented by the same company that sold you the old and now wants you to buy their newest thing yet again, that is.
I'm thinking of updating (computer and OS) when the next TES game comes out.
2 or 3 games? I don't quite understand the rationale you used to come to that conclusion. I think I own about 150+ games. Granted, most of them I haven't played yet. The ones I do play are mostly RPG's or tactical games. I also have the tendency to not buy them brand-new at premium prices, but to wait a year or so, until they've dropped in price. (Nowadays, this can happen through stark promotions on Steam and GOG and the like too, of course).
Most of my games I bought below the 10-15 euro mark, even. That's the way I operate, and I noted that for games from 2010 onward, it really isn't all that noticable anymore: graphics still look quite decent on full settings, and the gameplay is the same or better, with less bugs (thnks to the patches). The only thing is to have some patience but since I have such a large stock of games still to play, I can easily overcome a timeperiod of a year or two. IT's mainly a matter of not letting you be swooped up with all the hype, but for the rest it has nothing but advantages to wait a little.
Granted, there are a few exceptions, but as a whole, I don't buy games when they just come out: most are severely overpriced (imho). Which one can also see since in other localities, they're sold at a third of the price, often. Notable exceptions are TES games, which, I admit, the hype got me too (ever since Morrowind) - but then again, I clock more than 800+ hours on those, and some indie games I want to support, if they're reasonable with their pricesettings (like Torchlight 2 or the future 'The Bards' Tale).
And Vista works just fine, with those games. ;-)
Can't last forever, I'm aware of that, but that wasn't really the core of the problem I had. If the rule of Larian or its distributors was to give an EE version *in addition to* the old one, I can see nothing wrong with it, and they handled more than correctly. No complaints there. My case was something else entirely (but is more or less resolved, now).
