It's coming along well
I have been chipping away at a prototype for a Base Building/Open World/Syndicate-like with coop.
It even has a working stock market system, and if your extractors suffer a power outage, the respective resource charts crash.
Also, it has networked vehicles with multiple seats.
You can persuade and take over civilians, but I haven't worked much further on that system.
I'll probably see how Toplitz's next game (that vampire thing) handles minions. I want base building via minions (warcraft style) but I am not sure if its feasible network wise.
