You own the disc which means you own the primary method of software distribution which is that disc. When you buy digital all you own is a server approval to download and run what they say you can for as long as they say you can.No you fukking dummy.
When you buy a disc you don’t own the game. You own the right to play it. You always need to keep up with that disc to prove to the system that you have the right to play the game.
When you buy a game digitally, your right to play is proven in two places. One on the sever, and one locally. If you lose the server you can still play the game locally. If you lose your local save, you can still prove your right to play through the server.
Digital ownership gives you MORE options, not less.
Can you trade your digital game to someone else for a different game? Can you resell your digital copy after you've played it? If your game was delisted like PT and you lost the ability to download it how would you access it? Do you keep a physical drive with each copy of each game you get digitally?
On the PC side I can get new release digital games for a fraction of the cost a console digital game cost. Hell many of the new titles they give away free with graphics cards and you can buy the key on eBay for upwards of 30-50% off retail. PC digital and console digital don't compare. You can get games dirt cheap on Steam sales.
I don't mind buying PC games digitally because the prices I can get reflect that it's digital. I'm not paying $60 for a digital console game. Until prices go way down I'll buy physical.
