The post suggests replacing the linear congruential generator (LCG) with a permuted congruential generator (PCG). The latter has more random-looking output.

Another solution is to switch to a cryptographic hash function. For example, using sha256(seed || event type || counter) only requires storing seeds and counters in the save game.

This has several benefits:

  - You can find efficient implementations on all platforms without having to roll your own.
  - Gives the same output on all platforms by design.
  - Output is practically indistinguishable from randomness by design.
