It makes me sad that Call To Power has sort of slipped through the cracks of the various Civilization fan communities and has almost become lost to time. A few times I've come across lost people asking for help on CTP issues as they just didn't know where to go and ask. I hope to maybe rebuild a bit of a CTP presence on the forums and on social media so that CTP fans know that there's places they can go and talk about the games and get help on issues and exchange cool mods etc. Stopping the rot and righting this wrong will be a bit of a side project I plan to work on over the next few years.

In the meantime I feel it's important to build a database of just what's left out there so that CTP refugees can find each other...

Firstly where can fans even get the games now? CTP1 is stuck in licensing hell due to its use of the Civilization name however maybe with pressure GoG & Steam might release a modified version with the Civ branding removed. Thankfully CTP2 didn't have that problem so its available!

Secondly for forums this is pretty much everything I can find now...

Thirdly for social media groups there's an old reddit group and I'm working with others on building up some new CTP Discord & FB groups too..

Fourthly for patches/mods/resources we lost the old Apolyton downloads area a decade ago so I've been working to rebuild it at CFC. There's also some barely used ModDB pages that could be a good place for large mod files too!

Lastly amazingly the Apolyton Edition of CTP2 built from it's source code is still being worked on and some of the guys have been dropping by the new CTP Discord. They hope to fix CTP2's infamous multiplayer bugs in future versions.

I also backed up what I believe to be the last ♥♥♥♥♥♥♥♥ compiled Apolyton CTP2 Edition Revision 1111 release back in 12-Jun-2011 to CivFanatics here a while back:
