[Feature Request] Option for addition instead of multiplying. #37

Just thought it would be useful option to apply an offset to the amount of players instead of a multiplier. I understand why fractions wouldn't work (such as 1.5) but an offset would be a good compromise.

I'm looking for a small balance change, and multiplying is too large of an increment for multiplayer games, especially when above 4 players.

For example, being able to always set +1 scaling, so in a game of 3, it would play as if it was 4, and in a game of 7 it would act as 8 etc.

Thank you!
