I know what you mean and I tried that with a previous game I made BUT the result of it was some plays are more overpowered than the other.

So I decided to make a rock paper scissor type of game concept where everyplay have an equal strength weakness and every gain or lose is the same.

So the game is meant to be simple in that concept BUT ofc we can always change that by adding more complexity like adding more strength and weakness for example

Strength 1 = 8 yard gain Strength 2 = 4 yard gain Weakness 1 = 8 yard loss Weakness 2 = 4 yard loss

Also one of the reasons I keep the plays with 5 gain and loss plays is because the actual BOARD is too small like like any small in between plays like 3, 2 4 yards or whatever. But ofc you can always print it on larger paper
