I'm working on a game backend (which I'm finding Elixir/Erlang pretty good for) and I don't see how I could reasonably do this without using my own GenServers.

I'm working on a game backend (which I'm finding Elixir/Erlang pretty good for) and I don't see how I could reasonably do this without using my own GenServers. I can see not writing my own GenServer for webapps, but when it comes to concurrency webapps tend to be dead simple. Elixir is a fine choice for these but I feel like its killer features don't shine that much over the alternatives.
