SmollestLight: Unfortunately there is no way for us to increase that limit. =(
You mean the GOG store limit right?
That's odd, as other users told me they have a 5 copies per title limit and/or that they talked with CS and they increased their limit per title per day(forget if it was temporary or permanent).
Regardless, it seems the limit of one copy per game per day is tied to my card somehow, not GOG, so no worries.
(I was able to buy more copies via other payment methods)
BTW why is the game being delisted? If you could tell us and are allowed to, that is. Is it a new owner? If so, I wonder if it'll be back soon.
Aside: Thanks for replying so promptly to my last post here.
