I would say there was a good amount of discussion, but not an excessive amount. In most instances, the word pair meaning was pretty straight forward to interpret. There were some times that we had different interpretations of the word pairs, and there was more discussion that went with that. But, it was limited to us sharing our perspectives and agreeing that one was more likely, thematic, or interesting than the other option(s).

As an example, the trap scene was triggered with the meaning words 'military' and 'trap.' We all jumped to the same conclusion that the locals had some sort of militia and were intent on attacking us. There could have been other interpretations for sure, but our imaginations all went to the same place.

Later in that same scene, after we had talked down the attackers, we started negotiating and wanted to know what their motivation was. We asked for meaning again and got the words 'repair' and 'obscurity.' My buddies' minds went the literal route, thinking that the locals had some sort of technology that was hidden and needed repairs. My mind thought that perhaps it was metaphorical, and these tribespeople wanted to repair their society, which was forgotten about by the King and Court of Drinax. I presented that interpretation and my friends responded with a "yes, yes, that one" which is what led to us trying to recruit them as allies.

So yes, there is definitely room for differing perspectives and discussion. I suppose your mileage may vary on how easily other players might settle on a meaning. The Mythic book actually talks about having a caller for group play, so one player is delegated to be the one that decides which meaning or course of action the group will take, after hearing the options.
