I am currently doing this! Working on an MMO game server implemented in Elixir. It works AMAZING and you get so much extra observability and reliability features for FREE.
I don't know why its not more popular. Before I started the project, some people said that BeamVM would not cut it for performance. But this was not true. For many types of games, we are not doing expensive computation on each tick. Rather its just checking rules for interactions between clients and some quick AABB + visibility checks.
