I like how it seems like it's going to be a lasers and feelings hack, but it does something subtly different instead.
Mechanically, it seems like the strongest play is to have two characters working in sync, but only if they have a history of working against each other. The bit that interests me is that that attempt at prompting an emergent narrative, if that's what it is, requires proactive player buy in and commitment early on. Players could 'level up' in tandem by regularly butting heads, until they broke the game with their super high stats and could finally be BFFs. That's "the Nash" right there, and it'd be a pretty compelling dramatic arc.
