Swede in his early twenties here. Times are kind of irregular cause of varying workloads from studies, but I'm often on during weekends and around 21 on weekdays. Play most games "semi-seriously", like trying to win/beat harder difficulties but focusing on keeping it fun, rather than always playing the ideal way. Fuck around in games as well, but that's more dependent on the company, since it's always more fun with the right people. Could be down for being more try-hard in games like CS though, as long as the atmosphere is still chill.
