I wish that in the future developer can just host their own game with very minimum cost/overhead unless they really need some platform's backend feature. (multiplayer game mostly.)
For single player game I really don't see why it is so difficulty to host (even torrent it) would be a hard thing to do. During the shareware/pre-steam days where you may have downloaded the full game with a soft lock, I've played a whole game and then try find way to send my money as well. (was not living in NA at that time and there was no guarantee that a game will be imported with official vendor.)
