Other than the occasional tinkering with the Apolyton Edition of Call To Power 2 there’s not many CTP fan projects still going these days. However long time Civ community member Kull has been working over the last year or so on making the popular Cradle 3+ mods compatible with the Apolyton Edition of CTP2 while also making a huge amount of bug fixes, new gameplay improvements and even new custom terrain/city/unit graphics & animations. Recently he’s been posting about adding new custom wonders that appear on the surrounding city map titles (Civ6 style). There’s no playable release yet but any lurking CTP fans can find more links, pictures & info here.
