My friend moved from Hong Kong to Europe due to all the politics going on so he picked up CS:GO again (former CS:S player) for his spare-time after work and made some highlight clip from his first week. I bet he'd appreciate if you gave him a couple of views.
He has played CS:GO once or twice before like 10 hrs or smth but he grinded around 80hrs this week since his job doesn't start before 1.5 week
He has thousands of hrs in CS:S tho from back in the day. I was also suprised.
Because most family/friends is in HK so he needs something fun to do? I'm not gonna say that's why as I never asked but it seems pretty plausible, no? edit; he also said he had very tiring workdays so that might be why as well.
