Well I can still play Age of Empires 1 on my Windows 10 PC no problem, and that game is almost 20 years old! It's only DOS games that are a problem, Anything made for Windows 95 and after generally works fine, and I don't see it becoming uncompatible anytime soon.

Dos games are fine, just install DOSBOX... its really good :)

Yes they can espacially blue rays 100-200 years, just keep discs away from sun light. 

You list one of the most popular PC franchises which was devoloped by MS as an example for the rest of all tge games?

I have various games from windows XP era which are unplayable like Enemy Zero, Shadow of Memories, Breath of Fire 4, Oni, MGS2. 

Just downloaded Breath of Fire 4 and got it to run on Windows 10 immediately.  ¯_(ツ)_/¯

I'm hard pressed to think of any game released for Windows 95 or after that I can't get to run on Windows 10 natively. Star Trek Armada (2000), Rollercoaster Tycoon (1999), Zoo Tycoon (2001), Rayman Gold (1997), Civilization 2 (1996). I'm sure there ARE games that can't be run on Windows 10 that were released late 90's or after but the vast majority (literally 99%) work.

Even obscure Japanese Visual Novels from the 90's run.

While it's true that it is possible to make the games run, sometimes titles will have issues with hardware being far beyond what the title would expect to find inside a system, heck even my version of Halo 1 is convinced that I have 0MB of system memory when it goes to start up because of this, also there are titles which rely on older direct X video codec packages which have been dropped, say Dark Omen from EA, the title works and stages are fine, but any of the cutscenes are just a mess even by Windows 7, I fear what the title might look like in W10.

But yeah... with tinkering and patches/modding it can be possible to get games to "run" but with older titles you will encounter a few hiccups which can really take from the original experience, I'm sure if the PS4 could run PS2/3 titles but they were missing all cutscenes/music/sounds from the games... people would question the value of the ability to play those games, although it sure would make games like Metal Gear solid a whole lot shorter to finish, Silver lining on every cloud!

Why should there be any difficulty? It is already done on PC since forever ago, since they would only need to make one version with two separate settings depending on hardware?

Dumb move by Sony. By starting over you will be back to 0 each generation while Microsoft will be around 30 - 40 million regarding their last console which should run all the new games pretty well. Not to mention windows 10 PC gaming machine will increase their install base as well. Microsoft is really helping developers by making it easy to make games for xbox/pc and having a huge install base to help sell their games.

Nope, Disc rot doesn't happen only due to sunlight... It can happen if there is a scratch on the disc that allows oxygen into it as well as many other reasons... Just because its rated at 100-200 years doesn't mean it actually will last you that long... SSD's for example are rated for many life times but most ssds die within 5-10 years in real world situations due to the way that people use them.

First of all you pirated the game right now because it doesnt exist on steam or GoG or some other place to buy it it digitally on PC. So i am not sure if the game is modefied or not, but hey cool for you if it does work but doesnt change the fact that it didnt work for my PC Disc Version on Vista or 7.

Of course stuff like this can happen if you are careless, but you can lose also all your digital games if youre banned on PSN or Steam for being careless. So whats your point?

Blue Rays are also near unscratchable dueto to their disc protection, and scratches shouldnt cause this i dont think so
