Fair points for both, we're on the same page for the first point. GOG should be doing exactly that to mitigate the issue, and hope they have been but haven't been as successful with that technique. I'll give them the benefit of the doubt for it.

For the second, I agree that the majority of the issue are the storage space themselves, the others are tangential concerns. To me, a company that struggles to limit their file size has a poor take on how they implement features, it's a red flag that there are likely much bigger performance issues with the code. One doesn't mean the other has to exist of course, but they show up together fairly often.

I'm personally tired of game companies just throwing shit at the wall and not caring about the performance. They (well AA and bigger companies mainly) seem to have completely lost interest in doing anything other than the bare minimum. Does it work on the absolute latest hardware? Must be good to ship.
