Here are some of my idea's about for the Spore Expansion Pack

Ability to create and modify Plants, Planets, and Stars.

Have Knights and Wanderers have their own philosophies. (Philosophy of Chivalry and Philosophy of Exploration respectively for example.)

Be able to destroy the Grox Empire with all sorts of tools and weapons without any "Galactic Code Violation" backlashes.

hmmm, so many things that could be added.

Ability to create and edit plants.
Ability to make a fleet of your own ships rather than allies. (I have killed every alien race i encountered)
More complex AI in tribal stage. More items for tribal stage
A ability to enslave races. (slave camps and planets)
A larger cargo hold. (three times the current.)
10000 creatures made by people.
10000 vehicles made by people.
More cells for the cell stage.
The ability to get out of your ship and explore the worlds.
Ability to build space bases. (to replace all those worlds you blew up)
More plants species.
A shield that works in space.
Chat function so that u can chat to other spore players and buddies.
Remove securerom.
A improved save system.
A autosave function.
A way to remove evil incomplete patches.
A pyramid tool. (need to make some on earth!)
O yes. First person space flight. (would make killing the baddies really fun)
