I moved from my couch to my office and it's done wonders for my back. I have a Herman Miller in my office so that helps.
Once I did that, I figured - why not try PC gaming since I'm sitting at my desk anyway? I'm now spend about 90% of my time on PC gaming. Love it. The three things that really appeal to me are:
1) Full control over framerate and FOV, and;
2) A much older audience. It doesn't matter in 99% of games like COD where you can just mute obnoxious kids, but in games like R6 Siege where there is team killing, it makes a world of difference. I used to get team killed once every few hours on console. On PC? I'd be lucky to see it once every few weeks. This is no exaggeration in the slightest. A PC is like a $1000 firewall between me and those fucking children. How many games have team killing, though? So admittedly this is an advantage only a few games will benefit from.
3) RTS games. Guys, you guys have no fucking idea what you're missing in a good RTS game.
