I imagine I've signed away much worse in the game's license, but why even bother letting me know? (Or have I simply missed this the first 2,138 times I've played?) What was that screen about? Gauging how much more eye candy could be in the next expansion?
Let me recommend this: If you up system requirements at all, up them everywhere, Blizzard. Force upgrades to play. Ultima Online's latest update -- and the non-trivial blowback from their saying that (in five years or so, mind you) they might eventually finally toss compatibility with the original client -- should be lesson enough. If Windows isn't going to update frequently enough to keep Intel in business, why not you?
It had a cancel button but was up only long enough to glimpse it? Sounds slick. Blizzard says "Hey, we gave you a chance to opt out. You didn't click the Cancel button?"
