Imagine the fun we can have in human vs. human games.
You see a wormhole open up in one of your more isolated systems. Then, the wormhole closes. Hmmm.. that was weird, you think--assuming you even saw it happen.
Next you send your fleet through one of the 'default' wormholes in your system. KABOOM! They all die.
Of course, I would hope you have to un-cloak to lay mines...
