korell: Yep, I'm in agreement with this too. I have a limit to my net usage (10GB per month) so I sometimes have to plan large downloads. As such, knowing which games have been changed, by showing their version numbers, would be very helpful.
xyem: If we can figure out a way of confirming what games you have purchased, I could always send you them on a DVD to save you some bandwidth. Or if you live close-ish, I could bring them around on a portable drive (where you can show me your account first hand to confirm).
Many thanks for the offer, Xyem. :) I may have to take you up on it at some point.
However, all of my GOG games are currently downloaded and backed up at present so I'm good.
I know there is a website (saw the link on these forums) which lists the version numbers of the installers. And I checked my copies against it. From it I found that there is a newer version release of Stronghold (which I'll download later this month I reckon) and a newer version of Painkiller (my first GOG purchase but I've still not even installed it!). The Painkiller download is the big one that I'm leaving for now. I have an old version of it already downloaded but I'll probably look to get the new one before I play it.
Just seen the new release here on GOG today, too, and I will be getting that. But at under 300MB that is not a problem at all.
