You can’t compare it to TSW because that comparison is irrelevant, not because you are comparing it to a shooter, but because TSW is a failed game.
It is very important to compare it to other F2P games because that is your competition. TSW is not competition because the only money they have in TSW at this point is probably servers. In fact, I bet leaving TSW open is probably hurting them more than helping them (people that refuse to leave but would if no other choice). But leaving TSW open is more of a goodwill gesture than anything.
The important thing for F2P models to do is to be good enough that F2P players want to play it and feel that their grind is rewarded fairly. Why is this important? F2P fill the ques, buy things on the ah, make the world seem lived in. Those things are all important to whales. Without F2Players whales don’t invest. That is why a F2P game has to walk a fine line between generous and greedy.
