You think that's bad half my group pronounces Duchy as Doochey:D
Hahaha! My 10 year old nephew that I got hooked on Dominion constantly says "E State" for Estate. It's not his fault though, he's grown up in an age where everything that doesn't start with an "i" starts with an "e".
EDIT: Also...how does anyone say Doochy with a straight face? It just sounds silly...
