I thought it is already like that?
For games against the house, the concept is house edge.
For games between players, the concept is fees, usually taken from the winning player's share.
Which do you think is better from the players perspective:
This is a weird question considering that, if you are talking about a PvP, there is no concept of house edge (it is possible, but it not implemented since it will pretty weird, like roll between 49.5 and 50.5 and house will take everything, since that is not very encouraging to players).
and if you are talking about a game against the house, the fee and the house edge is literally the same. (You have both choices - 2x at 49.5% chance and 1.98x at 50% chance)
