Although it's not my place (I believe it is the forum leader's job) - Welcome to the forum
Serious Games is certainly an area a lot of companies do not persue, but I've certainly found it rewarding working on the TruSim team at my company. Trust me, when you've spent a long time assessing the nuances of what makes a face young, old, fat, thin, then replicating it in models and systems; you really begin to wonder why a lot of games characters look so generic and cliched
You may want to check out Sato Takahashi's work on Serious Games if you haven't already: www.satoworks.com - not bad for the guy behind all the character work on Silent Hill
I'd be very interested to discuss any insights on how you or your team achieve a sense of realism through either script or other systems - NDA withstanding of course!
