After buying my first pack of Baccus dwarves seven years ago, I have finally traded away the last of my 15mm ancients for 6mm WWII. So now all my fantasy, ancients and dark ages wargaming is now in 6mm as is one third of my WWII (IABSM, CoC is in 20 and 28mm) 

Alll of this to say that once Pete gets his tiny little 6mm hooks into you, you're doomed. ;)
