My first paradox game I have reached 100 hours in. I have officially passed the point of no return.

Congratulations! You have almost passed the tutorial! /s

I passed the 100 hour mark on CKII (my first paradox game), HOI4 and EU4 (still don't really get how combat works). Modding really helped with that.

Congrats, mine was CKII. I just turn it on and the next thing I know, it's been four hours.
