The only reason you don't want the game to be free is because you already paid for it!
Revenue is a costant stream dependant on community size, which has good chances to be pretty bloody big if the game goes free, plus if ads are done right they will take NO time since they would just be taking up unused space.
A free game with ads is going to make what? 1% of the fanbase leave.
The demand of money instead will hunt away a crushing majority of possible players.
Quit contaminating the issues with your biased foolishness, this cour should have none of it.
I am wondering where did you get those stats? 1% of the fanbase? Please don't randomly pull numbers out of your ass.
The demand of money is what that got amnesia, penumbra, terraria, minecraft the position they are in now, not free to play.
You are talking like commercial is evil, if this is the way, then your logic is clearly messed up.
In fact, I wonder if you HAVE paid yet, if not, you are in no position to question my motives where you just want to play a free game.
