First-person shooters. It's not just that I don't like where the genre has gone in the past decade (though I don't)... I can't even get back into the games I used to play for hours on end. back in my early adulthood, I probably threw hundreds of hours into multiplayer Unreal Tournament if you count its million mods and total conversions. Now, I have it installed again, I just don't play it often... and I'm not even very good at it anymore. Time was, I could make three quick-succession headshots with a sniper rifle while freefalling to my death. Now, I can't be bothered to try.
