I'm not so sure on that.
Of the people i encouraged to play tremulous and actually played the game, these are their reasons for rage quitting:
~40%"Players are given square guns which do no damage, aliens are overpowered, this game is unbalanced. Too outdated, poor graphics etc."
~5%"Alien starter classes are useless."
~25%"This game lags like shit"
~15%"All the admins on trem are **** and *** cause they're ***" [Even though only one admin banned them for like 15 minutes, they still ragequit. Hard to beleive, but there are people who can't tolerate teeny things...]
~15% Actually play the game for at least 3 months.
15% doesn't sound like much, but surely is greater than the number who actually continue playing...
These are not statistics, their assumtions based from all of the friends that i have that i recruited.
Besides, 95% or statistics are modified or made up.
