Not to sound like a broken record, but a work pc or regular pc has nothing to do with it. A gaming pc is just that, a pc with Windows, Steam, and games, nothing more. That's how you get stability. If you introduce a million variables like work pc's do, or overclock, tinker with game config files, etc, then sure you are asking for issues. But a gaming pc remains clean.
So in other words - what you're suggesting is treat and use the PC like..... a console.
A console sans the global username that works on all games, the consistant user experience, the need to avoid *ever* setting up any config files (probably with a mouse or keyboard), the requirement to ever take it apart and exchange hardware parts (like a newer graphics card), the beat 'em up or (other types of games that are not found on PC) etc...
What you have essentially demonstrated is that you brought *your* PC closer to the experience us console gamers have been experiencing since 20 years (longer if I include gaming on NES and SNES) - but in the end, it still doesn't match the console plug & play experience. And if you are used to certain types of games or certain franchises, then there is no reason despite visuals to go there that all.
To me, it's an apples to oranges comparison. Two completely different experiences. You are the one trying to convince that they are not that disimilar. Well, just by ignoring the points that I brought up where these two experiences differ, doesn't mean they are closer. These points may not matter to you, but they do to others.
Perhaps to avoid going around in circles:
With your PC - can you
1.) refrain from using a mouse or keyboard at all times?
2.) use wireless controllers in a plug & play manner?
3.) use a single gamer-identity across all games?
4.) download, install and play games without having to use a keyboard/mouse and edit config files?
5.) avoid having to set-up games to suit your gamepad?
6.) use wireless headsets that *just work*
7.) plug in and use up to 7 wireless gamepads and play games that are made for that?
8.) how convinient is it to do all that, without the use of a keyboard/mouse?
Even if the majority to those questions are answered by a yes - how long does it take to set up? And at that point, you're still left with a rather big noisy box in your livingroom and without the consistant experience. Some of us actually value these things.
I don't understand why people see this as the case. Many of us pc gamers became Playstation gamers first for the simple reason that it was available years before Xbox ever hit the scene. It wasn't Xbox that killed off pc gaming for many folk, it was the ps1 and ps2.
Killed off is a strong word. I wouldn't actually know. I would however care to point out that PC had online-gaming over PS1 and PS2. The Xbox was the first console that introduced online multiplayer out of the box. Then there's also the point that it being a console by Microsoft and the hardware that was touted as a 'very good PC inside a box', it immediately had PC gamers interested. The trend continued with games: Halo became the Xbox game (after it was cancelled for PC and PS2) and many developers followed as well, at the least by giving it support - perhaps due to the friendly hardware environment they knew so well, compared to the complex and complicated PS2.
If there is any weight to the whole argument - I would say the PlayStation market is a bit more diverse than the one Xbox had. This might have changed over the course of two generations, but back in the Xbox day, I think many gamers there were predominently PC gamers. PS2 of course also had its share from the PC crowd, but those probably left the PC longer ago (like me).
