Have you seen the Dune 2 mod for Rusted Warfare? https://steamcommunity.com/sharedfiles/filedetails/?id=1893092397
At the moment units seem to work nicely and look good. Only grievance is that carryalls don't work automatically. Multiplayer matches are possible.
...but in skirmish, the AI doesn't seem to care to build a refinery so AI matches are quickly over.
The mod is still in developement, so I hope that Skirmish AI and the automation of carryalls will be fixed.
