Hello @wzyas and welcome to the community! Thank you for your hint on CBA. Someone already tried to offer such a mod for 0 A.D.:  

Since so many TGs end without all 4 players resigning I made a classifier for my version of the local ratings mod. This could be made to be used as a victory condition. I am getting also annoyed by mates that resign too early. But some games are already decided long ago and if there is a huge dis-balance in the score and population one could already call it a gg: So for a clear victory condition one could set the score factor to 1.2 and population to 1.8 or so. Just as a suggestion for the game or a mod. I don't have time and the desire to code atm.

There was a mod in Age of empires 2 called CBA. I had tons of fun with it in 2008. Google  CBA (Castle Blood Automatic)    

Take in count pls I didn't see anything else about Carthage but the game before. Ah, in the video they mention "Delenda Est"
