Seeing what a roundabout method they took I fear a dumb a approach such as "-phase_city" is not possible. edit: I stand corrected, my dumb idea actually works.  

you should be able to do -phase_city <Requirements> <Techs datatype="tokens"> -phase_city phase_town </Techs> </Requirements>  

sure but wonder is alrerady P3 

@real_tabasco_saucecorrect me if i'm wrong but You can try specify same way is done on that template and it should override parent's requirements: <Identity> <Civ>germ</Civ> <GenericName>Cimbrian Clubman</GenericName> <SpecificName>Kulbawigô</SpecificName> <VisibleClasses datatype="tokens">Champion</VisibleClasses> <Requirements> <Techs datatype="tokens">phase_village</Techs> </Requirements> <Icon>units/germ/infantry_clubman.png</Icon> </Identity>  

So, my-mod is the top folder name for the mod, correct?   EDIT: Correct. This works. But will take a tooooon of GUI editing to make look good, because the current GUI code uses one font style for almost everything.
