ShadowWulfe: I'm not necessarily defending this one, just saying that they're trying something out. GOG can be kind of slow with deciding on a preferred way of doing things. I personally did not mind the increasing percentage off, despite most protests against it.
I think the problem most people had with the increasing percentage off was the range of percentages. There were a couple deals where the selection of titles wasn't the greatest with maybe 1 or 2 really good titles, but the minimum percentage started at like 30%. If the minimum started at 45 or 50%, I don't think there would have been as big of a deal made over it. The marketing of it wasn't great either. The promotion of "as much as" so-and-so percentage off had people going in with the expectation that they were getting 70% off only to find they had to buy 20 titles to get it.
As for this promo, I'm not particularly fond of it myself. I already own the first 2 Divinity games, so the only way for this to mean anything is to purchase at the 3 tier level, which really isn't a whole lot of savings (less than the lowest of those increasing percentage discount promos). Requiring the second tier for the actual new, most desirable game, really takes this out of the true PWYW promo type. If it was PWYW, people would be paying for Divinity 2 and then getting the first 2 Divinity games as bonuses. This is all backwards.
