Also, Reddit seems to be saying that European countries actually have a disc w/ the game actually on it. Just wonderful.
So, this starts the next problem w/ PC gaming at a retail level - what format should games be thrown on at a retail level? We obviously need something better for PC gamers (to hold the entire game on one or two discs, preferably one) and something cost-effective to dev's & publishers.
DVD - Still is fine for games that fit on one DVD. Most people have had a DVD drive or might even have an external; or some might have a BR-drive (which also supports CD's and DVD's).
Blu-Ray - Would've been fine for some games, with some games being able to hold 20-50GB of space or so. Games on 1 or 2 BR's are okay, but anything after that for install-switching could be annoying. Problem is that this format has not been totally accepted on the PC, thanks to Microsoft not winning the format war (HD-DVD lost) and since they don't like Sony (who supports BR format). Also, there's the other thing that digital distribution succeeded (so PC gamers buy their games there) + non-SSD hard-drives can be purchased so cheap for the amount of space offered that you can back a lot of huge games in one piece up on those (externals or internals). Blank BR discs ain't super-cheap yet to the public and neither are BR-burner drives.
USB thumb-drives - This is my solution for retail, if huger-sized thumb-drives would actually ever get cheaper. You can buy all kinds of different sized USB thumb-drives, so dev's + pub's could always find the size to throw the game on that would have enough space to toss the game on. The biggest problem here - bigger sized thumb drives ain't probably cost-effective yet for pub's, so there's a problem there. Most PC's have USB, so this is an easy solution for the supported format. Games at a retail-level likely could be placed in much smaller boxes (than DVD slim-cases) with thumb-drives placed inside of these boxes, which could make retailers happy as they'd likely take up even less space on the shelves. But, again - thumb-drives would need to get cheaper first.
