here's the real issue, you like quake? you want to play quake? then @#$% play quake.
you want more people to play quake? tell people about it, show them the game.
as for what makes csgo and games like dota so big, it's convenience you can just jump on hit enter queue and you will get a game loaded up moments later. make a proper matchmaking system for quake and people will probably play it.
why sit around and wait for "the next big thing" when it comes to arena shooters, when what you already have is more than good enough, and no I'm not expecting some great comeback story for quake.
If people want change you can start the movement yourself, you love a game play it.
