I had about half of an essay-length post that was just going briefly over everything we'd need in a 4X game... dunno if I should post what I have, try to get around to finishing it, or just forget it...
I would like to work on the ship design aspect of the game, though... that's my favorite part of any 4X game, getting those cool new techs and putting them on my massive fleets of doom (or in my case, pathetic squadrons of wussiness

), then pounding away at the enemy hordes (or plinking them with my peaguns while their shields regenerate faster than I can hit them

)
Anyone else have a favorite area they'd like to work on?
