This is RIDICULOUS. I can't have dozens of consoles and then dozens more backup consoles for those in my house. I don't have the space or money. I also don't want to lose access to my old games, because (duh) I care about the medium. I'm moved by games. I have fun with games. I don't want to lose access to them anymore than I want to lose access to a beloved film.
And here they're not even TRYING. Come on, Sony already has a PS1 emulator running on PSP, PS3, AND Vita. They can't at LEAST port THAT to PS4? If you can run it and run it well on PSP, you can sure as hell run it on PS4.
Microsoft owns all kinds of emulation and VM tech, and is actually RUNNING a VM on the Xbox now. They already have a decent emulator for the Xbox 1 running on their last system, and their new system USES THE SAME CPU ARCHITECTURE AS THEIR FIRST SYSTEM. At LEAST get us Xbox 1 games running on One! I'd think the GPU portion of it shouldn't be much different than doing it on 360, and the CPU portion is actually easier...spin the game off in a Xbox 1 VM and let most of the CPU instructions pass right through to the underlying CPUs.
Okay, granted, emulating Playstation 3 and Xbox 360 is harder. I'm honestly unsure what the CPU situation is like. The new CPUs are more powerful, more modern (and in the case of One, more of them), but still, they're clocked at half speed, and I could conceived of special situations where despite the new CPUs actually being considerably more powerful, specific ways they were used (particularly on PS3) actually makes running them on half speed CPUs hard.
But geez...at least make a commitment to keep bringing along compatibility with all your systems prior to the last one. At least give us Xbox 1 and PS1/PS2 compatibility, and give us 3/360 on the PS5/Xbox Two.
It's making me wonder if I wouldn't be smarter to just get everything for PC where possible, as while backwards compatibility is far from perfect, it's way better than this. Many (probably most) Windows 9x games run on Windows 8. Most anything for NT runs on newer versions of NT. Even older DOS games are pretty much fine thanks to the amazing DOSBox.
End rant (until I decide to rant about One's sealed hard drive and 4's idiotic sealed proprietary battery in the controller, or One's use of a significantly whimpier GPU to push the ridiculous Kinnect *sigh*)
Now, on to play Thief LOL
