The price is fine but the discounts are super meagre. Today it's an amazing 15% off, 5% more than I've ever seen it before. GIve it a year and maybe we can get 30%
I think the price and lack of substantial discounts is on Blizzard/Activision, not GOG
OP believes you shouldn't have to wait more, for a nice discount, as there was a gap of (nearly) 23 years, since the game was released. I agree. If
you're going to offer a discount, it's about time to do something actually nice.
At least, there's no risk of you losing installation disc(s), the game will stay forever in your Gog account (even if Blizzard decides to remove the game, from the store).
Also, if you want to see Diablo II / LoD here, it seems to be a good move. Blizzard won't consider bringing the classic here, if there's barely any interest in the first game, I think.
