Sarafan: Server space is a lesser problem here. The bigger issue is data bandwidth. But I don't think that the offline installers will disappear. It's a too recognizable feature to get rid off it.
Thanks for the reply. To me though that highlights the paradox of prioritising Galaxy over offline installers. Example:-
Person A - Downloads a "finished" game via offline installer, installs it, plays it, uninstalls it but backs it up. Then perhaps wants to replay it every 2 years (from backed up offline installer). After 10 years, he's enjoyed 5x replays from only 1x download.
Person B - Downloads the same game via Galaxy but uses it like Steam (installs it, plays it, then deletes it, then re-downloads, then deletes, then re-downloads then deletes, etc). Then perhaps he too wants to replay it every 2 years. After 10 years, he's enjoyed 5x replays from 5x downloads.
^ Person B (Galaxy user) ends up requiring 5x (+400%) more server bandwidth / load than Person A (offline installer user) for the playing the same game the same number of times. If server bandwidth is the main cause of GOG's significantly increased Selling Costs, if anything I would have thought GOG would be more interested in benefiting from the huge savings in server bandwidth that come with promoting the opposite (GOG's unique feature in not needing to re-download on every reinstall)? I really can't see any other answer to
"The more GOG push Galaxy, the higher GOG's selling costs seem to go" in the long run.
