He showed both his Warhammer 2 and his Warhammer 3 steam page with the hours displayed, live on stream. He's been a tester for Warhammer 3 ever since the first stage of testing. Now of course, the 13,000 warhammer 2 time on his steam page isnt proof that he played 13,000 hours of the game, who knows, he could have simply left his pc on running warhammer 2 nonstop whilst he slept each night etc. Of course he is also a twitch streamer who exclusively streams Total Warhammer every day as his main source of income so I imagine he probably does indeed stream at least 8 hours a day, every day of TW2 (or did prior to TW3)
