We’re probably gonna keep CF3 up as long as it’s still played (the same with CF2).
We might also only launch in certain regions for the new game so people should still be able to play the older versions.
The new game is also gonna be way different from the older versions.
I expect only 50% of the current users are gonna switch.
For the user that continue to play the older versions we have to keep the game ‘balanced’ and making everything free would be a bad decision as they would then quickly die.
If there is nothing left to unlock (no more progression) your only goal left is to earn ranking and for most players this isn’t enough motivation to keep playing.
The new game will have a lot more objectives and goals so you can continue playing for years if you like.
