Thanks! I should have been more precise and said that each player's LiveView socket is a separate process, and each game is a PubSub topic. But yes, games are persisted in a database after each move so you can close the window, come back later, re-join on your phone, etc, just like you'd be able to do on chess.com. So games that are abandoned currently stick around in the database, but don't keep a long-running process up unless someone actually has their browser open the whole time. Games with a timer (regular games that were started with a per-move timer and all tournament games) eventually time out in a loss for the player who let the clock run out, but those stick around as well - you can view replays of any finished game.

Deploys and restarts don't impact too much - sockets just reconnect and the state reloads from the db.
