Agreed 10,000%... It's the biggest problem with the push for digital only games... When you buy a digital game, it's license is stored on your email account that is associated with your account, Xbox, PlayStation, or even Nintendo. They all run the same way, you need to logon with your email/password that you got the game on to be able to use it.
So, if that console of yours gets dropped into your basement, as the Xbox 10 comes out or the PS12 hits the market, then you change your password ONCE in 15 years(I'm sure it will be changed many times over that time), all that content is unusable and gone if you just give or sell that system to someone else. Bye bye classic games....never to be seen again from all those things you paid for.
If you read the fine print, Microsoft's is pretty much the same, so by buying digital only, you take the risk of that content no longer being available. As for updates, yea that stinks but, if the game was playable with out a patch, you should STILL be able to install it and play it. If you only by digitally, and your system dies when you boot it up 20+ years from now... Oh, well.
Now we look over modern games, The funny thing, 25 years from, the ones who collected the boxed/retail copies will make money off the classics. If I walked into a yard sale, and saw a console. if it was just a console, it's meh but, if it's got a bunch of games, it's a whole different story.
I play classic games and have a pretty large collection of classic consoles but, I also play the current stuff. 85% of my games are physical. There is a few like a COD or something where 1.7 billion were sold and I will play it a lot, I might buy digital but, most of the stuff I will go to the store/online and buy.
It's something game collectors should really think about when they are on the fence of buying a digital game...
