So, I'm not sure that personally I would like an improved version of AC now. At the time, I really liked this game with innovative gameplay changes. Much more than CivIII, released around the same time. The most valuable innovations that I remember are the 3D landscape, which has a vertical dimension, as well as the unit system based on the creation of "prototypes" (the player could create his own unit with completely arbitrary characteristics). Of the funny details, I remember "planet booster" and "nerve bonding for drones." )
However, the gameplay itself was based on giving each faction individual characteristics. Something similar was then implemented in all new versions of Civ, and this was one of the reasons that new versions did not become interesting for me. I've always been of the opinion that differences between factions/civilizations should be minimal and purely decorative. I know that most players take the opposite view, which is why these differences are persistently introduced into the gameplay of new versions of Civ. This is partly why I like Civ2.
AC became a one-time game for me, which I also never returned to. Although I have a working version of AC on my PC. A few years ago we even tried to play the multiplayer of this game, just out of curiosity, would it work. It seemed to work great, but the game itself wasn't appealing to me. However, as far as I know, some players even now play the original AC. I think your project will be interesting for them.
