Is it cheaper data wise to delete a lobby and recreate, versus reuse?

I have a 2 player game like tic tac toe for example.

if the client disconnects, the easiest solution it seems is to just delete the lobby and the both the host and client can search for a new game.

or I can have the host wait for a new client to join and start a new game but this will be more complex programming wise cause I’ll have to reset stuff maybe

it’s easier to just destroy the lobby and return to the bootstrap scene.

but will this constant creating and destroying lobby be more expensive data wise versus maintaining an existing lobby?

For something this small you may as well host hundreds of lobbies on one server(executable), that would be the most ideal route.

I don’t know how to manage server stufff lol
That’s why I’m using unitys systems.
