My time exceeds 900 hours in ETS (since 08.2016) and 800 hours in ATS (since 02.2017), so all of us are casual
*TS gamers, since there are people who can make 1200+ per year*

, which actually can be dangerous for their health.

ATS was almost identical to how I started watching the
EqG

*(some crazy dudes who make 10-12-hour streams are probably among them)
