The dichotomy of interest isn't really NNs vs GAs but about stochasticity vs determinism. The user/player doesn't care which it is until they learn to see the patterns and to reliably exploit the rules. Once you notice these patterns, the spell is partially broken and immersion is compromised. That's part of the reason stochastic methods have been such a hit throughout the history of game development for NPC behavior.
