Age of Empires: 4 Open Source Clones Compared
None of these three currently offer a complete, ready-to-play recreation, each for a different specific reason. aoe has only very basic gameplay implemented and only in multiplayer mode — single-player is simulated by hosting a session and adding computer players whose AI just gathers resources until attacked. Chariot's last stated update (2016-07-08) describes only a demonstration of the original assets loading, with no playable game yet. openage has by far the largest contributor base and has already built out a modding system (its own 'nyan' content format plus a Python scripting console), but its core gameplay simulation is currently non-functional while it's being reimplemented from scratch.
