You are a star for loading these Early Bronze Age (EBA) games up to the site. I have an extensive collection of 15mm scale figure armies to play C&C on a hex mat and the EBA is one of my favourites. I have published and article or two in the Society of Ancients magazine Slingshot using C&C for the EBA. In the past I have utilised Punic Wars maps and substituted the figures around. Elephants for example become HCh (battle cars), sometimes also Heavy Infantry and Heavy Cavalry as well if I think the gamers might like to use even more battle cars. Numidian Light Cavalry become Light Infantry with javelins. Otherwise, all the Medium, Warband, Auxiliary and Light Foot are like for like swaps.
