game_id

[Amadox]

There doesn't seem to currently be a way to grab the game_id other than copypasting it from the console, or brute-forcing our way through the matchmaking api's server list. It'd be neat if we could access it via the Modding API, so we can:

a) request it from within the game via a /c command
and
b) request it via mod (and then for example output it to a file, or whatever)

There is no and can't be game_ID, but you can count trees in first chunks, position of every tree here and position of first player after 30 seconds from start.
In this way you get some unique information, which can be used for unique save game name.

The map seed is the best "game id" that exists.
