I'm currently dealing with a multiplayer combat system where the damage dealt by the players is always multiplied by a random factor between 0.8 and 1.2.
In theory, a truly random RNG may eventually yield the same number many times (see the Tetris dilemma). This could result in a match where player is always making very high damage while the other always makes very low damage.
What can I do to make sure this doesn't happen? Are some RNGs better than others at avoiding repetition?
