new method on game, actor(entity) or something, to only allow the owner to use a private company ability out of turn

[michaeljb]

Could perhaps restrict this in Actionable?

some notable exceptions to actor == player

• 1889 Ehime Railway - the private seller is the actor
• corporations in receivership - all players are the actor
• 18CZ 2p, Vaclav's OR turns - actor depends on OR step and priority deal
