next title was Legionnaire which used the same graphics system and UI to
recreate Roman legions fighting barbarians. They key development was that the game was real time.
Between these two games, you have most of the ingredients of today’s
RTS games.

You'll need to download an Atari 800 emulator and system ROMs. There are several available but the one I used is here. There's a copy of the game's manual here. Finally, click here for a pretty comprehensive library of games. To run the game you have to load the .atr game image into one of the virtual disk drives and reboot the emulator.
