The prologue will be completly removed from EB in 0.81. To do it in EB quality a Sons of Mars style campaign would require a new map, adopted scripts, lot's of research for accurate starting position, family members etc. or simply would require to many ressources that would lack to complete the main campaign and some EB members more interested in other areas could claim a provincial campaign for them as well.

Also a conquest of Italia campaign would overlap with the main campaign. A carthage vs. Syrakus campaign on an enlarged sicily map would perhaps be better suited.

Generally I think it would be very nice to have provincial prologue campaigns, would be something great for a minimod, maybe a simplified camp. without scripts. Something as Spoonfrog's Sicilian Campaign Map for vanilla R:TW from 2005. Before I joined EB I had begun to enlarge to include carthage and planned an EB version. Would be fantastic if somebody could something similar.
