Perhaps somebody should explain where to find this?
I've never seen it.  

 Pictoquest 

I was wondering if Pictoquest is worth a small mention. For those that don't know, it is a joke RPG similar to Mornington Crescent (game) that has become well known on Gfaqs. 

 ad-hoc or internet 

can pictochat only be used in ad-hoc connection mode?
