There was this first person shooter called Solider Front that I played religiously from 2nd grade until my freshman year of college. I think I averaged at least 5-6 hours a day playing and played every almost every day so I probably had well over 10000 hours in it. My most played game that I actually have tracking on (via steam) is an idle game called Idleon and I currently have 4000 hours logged on that. Although if I add up all the hours that I have spread between steam accounts for Rocket League, that total is probably around 5-6000.
