At least once I'd seen Asterion get huffy after the drinking game. I forget what choices I made to get there.
Not sure if that would get longer term consequences.
Well, I just answered honestly, as me. It was quite innocent. :) However I assume, there can be consequences. But the main idea is to create some dialogue choices that are there just for the flavour of the game, and don't bear any long-term consequences, requiring to create spreadsheets, having track of dozens of possible branches, etc. :)
