Not yet playable. Great potential. Best choice for play by e-mail.

SE5 has definitely a great potential for multi-player. I think it is the only 4x game which supports a good implementation of parallel turns. With parallel turns you can process the commands from every human player in the game simultaneously, without waiting for the game turn to circle between them like in Round-Robin games (the civilization series most notably). This greatly improves the pace of play by e-mail multiplayer games.

If you happen to have played Space Empires 4 in multi-player with friends you'll be certain about how addictive this game mode can be.
Playing over the e-mail is fitting for people lacking fast connections and time to play on-line and it conveys a very funny experience without forcing you to make rushed decisions to overpower the speed-clicking skills of you competitors.

The AI is crap, this game is made to play via e-mail against human players. The single player game mode is just an extension to the tutorial, and it should be considered just an add-on, not the main feature of the game.

The game is too bug-ridden to be playable, even in multi-player.
You'll have to wait for a patch or two...
