Multiplayer Support for Old Versions?

[nolannorwood]

Hi all,

are there any plans to disable multiplayer matching servers for older versions? We're running a heavily modded game (~150mods, 500 ingame hours in) which we cannot easily upgrade to the latest version. (or is this version independent anyways?)
The main reason to try upgrade would be, if we could expect major UPS boost, doing approx 25ups on a 3900x with 32gb 3200mhz on a dedicated headless ubuntu server, which is getting more and more cumbersome, but from reading patch notes i do not expect it?

Thanks for creating such a marvelous game.

The matchmaking API has not changed fundamentally since the 1.0 release - I doubt there are any Backwards-incompatible changes planned. If there ever is a change, it is only a matter of providing a list of Server Connection URLs; you could theoretically re-implement an open source server browser with some work. The server-browsing code in the game is separate from the Client-Server interaction code as well, so new game features won’t cause problems either.

There HAVE BEEN changes to the Game within the 2.0 release cycle to add new features, most notably is that TLS Certificates are validated. This should not cause any problems for Older Game Versions, since it is a “client side” check.

Without inspecting your Save File & Mods there is no way to know how big of a difference upgrading to the current Stable or Experimental would make. It is completely dependent upon the Versions being upgraded from/to. On long-running Multiplayer maps there are usually MANY idle or inefficient sections of the Factory which can be deleted. You can even use Console Commands to delete “unused” chunks of the map.

Good Luck!

Factorio multiplayer games are self hosted. If the official public server list provided by wube goes down, multiplayer games will continue working.
