I have played Eve Online so many hours, and it’s a bad game. Don’t do it. you will spend hundreds of hours dreaming about the cool thing you’ll do later, but for 99% of players the cool thing will never happen. You will be part of the one percent’s cool thing.
Do you have a similar game?
(warning: link to reddit) - the thread is ~3 years old, so it sounds like your rough calculations are correct.
I’m just a filthy casual, so I never had the skills to tame high level dinos and stuff, but this game was still such a time suck! And so frustrating yet addictive.
