Two or three things come to mind...

250k viewers in total, just FIVE THOUSANDS to the 2nd place? How's that possible

Do\did any of these CS pro play QL?

Game was a snorefest to me.. Ppl going nuts for some shots that looked like 1500 ca elo to me.. Maybe i just lack the knowledge to understand how deep the game is teamwise.
How is it possible that this game is so healthy compared to quake? Is it just a matter of accessibility and a slower pace? Quake was much much slower back in the days when Q3 was actually big.

Was spamming C O O L L E R in chat and nobody counter C O O L L E R'd :(
