Ok not sure this is the right place but anyway,

I got the retail version (european) of Medieval total war 2 and it saids on steam that kingdoms will work with the retail or the steam version but when you go to Medieval on steam it saids that you need to buy medieval the as you did with kingdoms? Seems like a bit of a contradiction, so anyone know what the deal is?
Am i better off getting it retail? will things like modding be un-do-able with the steam version?

Cheers,
