I noticed you have your game on Steam. Did you end up using any of the Steam networking features via Steam SDK and Godot Steamworks?
I'm using ENet for my RTS project and found that Steam's networking code offers many of the same features offered by ENet (including the reliable, in-order delivery of packets, which is invaluable for an RTS Game). I was able to abstract things out so that my game uses ENet on LAN games and Steam networking for online games, and the rest of the game code is none the wiser.
The Steam networking sockets do offer the same functionality as ENet. Is it possible to use the Steam Datagram Relay without the steam networking sockets? I would assume so. Not sure I see the benefit of supporting both.
