This is a simple Real-Time Strategy game played by AIs. Each player gets a factory which constantly produces units. Units capture generators. Generators provide resources to produce users quicker.

To play the maps/cross.yml map:

git clone github.com/46bit/rts
cd rts
bundle install
bundle exec ./bin/rts maps/cross.yml

The game will increase its file descriptor limit to the maximum possible, but you will encounter problems if you have more units than file descriptors. This is due to a font handling limitation in the rendering libraries used.
