We have to sacrifice the cost of having some games not on the roster because we don’t have the time to do a tournament for all of them. Granted there is always free play. PC has reduced the number of tournaments and now consoles are doing the same. Just so we have time to finish the tournaments and to foster free play time into the LAN events.
If we added every game we wanted to play to the list of tournaments, yeah it would draw masses of people. But we don’t have the time to run 20-30 + tournaments.
