I find F2F the epitome of that. A combination of the Live Time Pressure aspect, but also physically interacting/seeing the other person. If someone does something stupid or isn't talking to me in a live game on webDip, I have to just chalk it up to either bad internet, stupidity, apathy, etc. But in a F2F game I can figure out the, for the engineers on the site, failure mode (only talking to a select few, not confident enough, not knowledgeable enough, overwhelmed, old-school player, just here for giggles and beer, etc) and that gives me the opportunity to change how I approach things. It's near impossible to find the failure mode through a screen compared to F2F.
