Just out of interest and after reading this post
It does appear that the original 'Mount and Blade' can be activated
with a 'Warband'
What use is it?
> None if you use the GoG installer - none of the games need serials for single-player!
> Very useful if you don't use the GoG installer i.e. -> enchanced edition
-> which gets you modding support for certain mods. Essentially then, purchase 'Warband' from GoG for the serial key - get 'Mount and Blade' thrown in for free! Save yourself £6.19 (current offer price £3.09) I presume the official (outdated) download from the Taleworlds site would work too!
