I always thought the "idle" emote on the overland map was biting nails, but maybe you're right! I'll try and look mote closely next time!
Ahh Quest for Glory. One of my all-time favorite game series as a kid. Mostly because of interactions like this. Now that's an IP that I wish someone would acquire and reboot into an mmo.
The original creators, the Coles, are working on a new adventure/RPG game called Hero-U that's to be a similar style game. http://hero-u.com/ There was a fan remake of Quest for Glory 2 that's available for download, and you can always find the original series on GoG.com to replay http://www.agdinteractive.com/games/qfg2/
I agree it is gross. I would rather it was just an emote to do in joking not an automatic thing our character does lol. Where's our dignity? OMG Get a tissue will you.
Upcoming Tailoring Recipe: the Handkerchief. Keep one in your inventory and the emote changes to blowing of the nose with the Handkerchief.
