And one module I've avoided as a result of hearing the horror stories. To the point I admittedly forgot about its existence. In the case you mentioned, they need to get done. Upgrading CA and ground physics can be done at the same time. Or just the physics. Regardless, they'd need to want to do it and start. My impression is CA hasn't changed for a while. And I'd agree. Hard to dream of full tank simulators if the simplified ones (CA) aren't great to play.
