I have been PC gaming on 40+ inch TVs since they got HDMI ports. Easy nearing 10 years now. Play everything on the 360 controller. If the game does not support it I use xpadder to map it (Got to lvl 85 on WoW doing PUGS with the controller no problem). Only first person shooters in multiplayer are a problem as KB/M stomps the controller for that unfortunately, so I crack open the PS4 for that fix

Just bring your PC downstairs, or treat yourself to a nice big screen in a bedroom.
