Which is strange because I find older games easier to play as they don’t require any sort of internet connection or mandatory patches. The entire complete and finished game is on the disc/cartridge.
It’s modern games (post 2010) that will become the problem in future as more and more of them only contain a small portion of the game on the disc and the rest must be downloaded.
That's what I'm thinking, that they're focusing on just the legal methods. Emulation is thriving, and only going to get better. The main thing I would say is dying out, rather than old games, are CRT screens to play them on. The prices have been skyrocketing for old TVs in recent years, in this area they were being thrown away and now everyone seems to be selling them instead and getting decent money back.
The reason I bring up CRTs is because old pixelated games LOOK SO MUCH BETTER! The games were made for the colour bleed and such, where the artists of the time really got creative with how to use blurs between pixels to their advantage (Castlevania is one game many people use to compare CRTs to LCDs).
I would hope some company can start making them again to sell to enthusiasts, brand new CRTs, but unfortunately I can also see this being incredibly expensive to do so in this day and age.
