Boy i am getting myself embarrased... Just 30 hours.

almost 2000 on steam but I 100% confirm I have way more than that on the game in general

2500 hours lol

a worrying amount due to season 4

approximately too much

A lot.
Around 1.5k.

Its hard to say for me because i've never used the steam version and 8 years is a lot of time but comparing to the other games i've actually been able to keep track of my best guess is 4-6000

I used to spend all my free time (which mostly all my awake time) just playing this game for YEARS
and i have no regrets

At least 2000.

I'm really bad at approximating how many hours I've sunk into a game (I dont use steam)

4.7k on steam

2000 hours via steam.
