		emj on June 2, 2022 \| parent \| context \| favorite \| on: Ask HN: Favourite open source game? XbattleAI did a TCP connection version, I can't remember if it was good enough. See. https://github.com/robertjschulz/xbattleai The closed source javascript game https://generals.io is a good simplification of XBattle, I've seen one OSS server reimplementation of it. If you can find the code for Europa I'm interested, I think it was released as OSS but I couldn't find it when looking around.

It wasn't opensource ... till the author decided to just shelve it. See above for download link.
