[Phoenix-D]

If you're willing to do pre-game set up, there is a way to make "disasters", races entering via newly opened WPs, and such.

Take one race, create a new racial tech. Give this tech extremely overpowered, cheap components, and impenitrable cloaking. Give it a 1 MP engine.

Now, you set things up by creating the game and "idling" all the other empires while the dummy empire's ships are moved in position. What you need to do is decided when you want your "even" to occur; the event can be anything a standard empire can accomplish. Move the dummy ships that number of spaces away from the target, and give them orders.

Once everything is in place, nuke the dummy's colonies. The ships will contiue on their merry way and fire your events. This works best with exploding stars..
