1. coolmaths games where i have spent around half of my entire existence playing
2.i has played 2,516 hours playing the worst called gmod.

Definitely dark souls 3 for me, that game is amazing.

Pretty much my entire childhood revolved around Ragnarok Online. So I guess more than 1000+ hours.

I love guild wars 2; I think i spend like 5000 hours on that game

ff14 I have 1000+ hours. I also have almost 1000 in gmod.

Probably thousands of hrs on Minecraft. Sadly you can't check total overall playtime.

Europa Universalis 4 with 2266 hours and still counting.

yes good game like me 1200 hours.
free to play thanx

Currently up to 1864 on my main R6: Siege account. Have 2 alts, so probably around 2300-2400 total if I had to guess. I probably played more than that on the original Rainbow Six: Rogue Spear. Played that like 6+ hrs a day, 5 or 6 days a week all through high school and college.
