Hmmm.... How to break SE4:
1 Mod a ringworld-killing component.
2 Build lots of construction bases over a star, with plating/ cable/ ringworld generator ships on repeat build.
3 Let X=1
4 Construct a ringworld.
5 Destroy it. Note that it leaves an asteroid field.
6 Place a star on the same square.
7 Turn the asteroid field into a planet and colonise it.
8 Turn the star into a ringworld. You now have a X planets and *and* a ringworld in the same sector.
9 Let X=X+1
10 Repeat steps 4 to 10 until X is equal to a few hundred. Open some warp points from that sector as well, and chuck in a few storms, just for good measure.
11 Save the game.
12 Persuade an enemy to attack this sector. (Or gift one of the planets to him.)
13 Point and laugh as the game tries to fit way too many planets, ringworlds, warp points, ships and things into the combat map, then collapses spectacularly. [img]/threads/images/Graemlins/Grenade.gif[/img]
14 Post the savegame to this forum so we can all see it for ourselves.
Don't forget to convert all the planets to your native atmosphere, max conditions, population & value, and then fill them with monoliths.
