I have never really looked into BGP. ( never needed to ) But clearly at the scale they are, there are risks and they didnt plan ahead.
Did I mention that I got my GOG version of the Gold Box SSI AD&D games installed and running on my Pi400+?
They say they support Linux on certain Gog titles - but their installer only supports AMD/Intel Linux distros. But most of the titles that they say support Mac/Win/Linux are DosBox games. They wrap everything in a package and then launch it in DosBox on whichever platform.
So I figured out how to install DosBox on Raspberry OS, then copied over the installed package from the GOG directory - and it works... pretty damn well - too.
They should really make an ARM package that would support Pi... that has to be a huge untapped potential market for them. Tons of people with $115 computers who are craving commercial gaming experiences - and they're just leaving that money on the table.
The cross platform DOSBox titles tend to be bargain titles too. All 6 SSI titles are in a bundle for $9.99. That is months of gameplay for $10. Sure, it is gameplay like it was 1999... but if all you've got is a Pi... you're probably OK with your titles being a little dated.
