As a player, I want to be able to request being substituted, just as easy as I can surrender.
- because I want an easy way to be replaced, without requiring me to talk with the host or to submit tickets
Once I have made the request, the game should be listed in the “In-Progress Games with Open Slots”
- the game continues just like before, I can still make turns in that game while I’m still a player
Another player should then be able take my place just as easy as joining an in-progress game is today
- optional: force or let the player decide if the “minimum 500 turns” condition should be respected
