I’m cross-linking this topic to another where the new gent said he got futzed because a game he tried did not understand TALK TO. The TALK TO / (other communication) binary seems to be at least partially responsible for this split on getting through Navigatio.
I know his game was from the 80s, but I think the upshot is - players are best off knowing of both. But ever more bester ofer is games indicating which they want.
