gameplay options

i was wondering what people would think about adding more game options?
for instance (these are just a few of what i would like to see in rebellion)

controlling what ships are allowed

adding a time limit to the game

custom objectives

controlling starting number of planets under control

in capital ship victory, choosing what capital ship you get.

one i really really want to see is being able to make custom maps where you can place the planets, and have custom objective, and events happen when certain planets are taken.

i also wish there was a campaign.

of course there are problems with such as making only capital ships available means getting the "go big, or go home" too easy. and unless the developers are amazing, AI wouldn't be able to work out custom objectives.

thoughts? opinions? problems and/or solutions? other ideas to add? and there better be someone who disagrees with me
