The amount of money you get for custom games is really low so we designed it this way.
You don’t gain rank or anything, just a little bit of coins as reward.
The coins you earn is also only as if you played with 1 player.
Each player earns it’s own coin reward but in the end it’s divided by the amount of local players.
So if you play with 2 players and player 1 gets 20 coins and player 2 10 you only get 15 coins and not 30.
I can not give any information about the features and/or mechanics in the new CF.
