Nope, I have been a PC gamer for about 30 years and I love emulating classics from the past. It’s not as challenging as folks around here seem to think. I guess sometimes people just have a hard time accepting that there can be multiple ways of doing a thing, even if they are unaware of some of those ways. Emulating XP might seem like a big deal for someone who is new to the idea, but personally I have been emulating XP for decades, even when it was the modern OS, along with many other types of OS, so it’s a matter of rote for me at this point. I wouldn’t even consider XP to be old enough to be a challenge - try emulating some of the original Linux distros, or an OS you’ve never heard of for that matter. That’s where the challenge can come in.
I love that so many people have an opinion on this subject though. It just affirms that new ideas are out there for those who want them. Happy learning!
If you’re just wanting the functionality of a Steamdeck on some other device, there are a variety of ways to accomplish that. If the other device is an Android, you can just install the Steam Link app and you’re off to the races. If it’s something else, depending on the device you can probably get Moonlight running on it, which will accomplish the same thing but will actually have more versatility than you’d get with a Steamdeck anyway.
