Yeah, also "god techs" like he says.
I want diplomacy to be basically ripped straight from Civ4, with all the options and such :)
I also want as you mentioned, super techs, but i want them to be researchable so an empire could focus all its efforts on discovering that elusive "wunderwaffen".
What kinds of supertech? Well, rip em straight from Space Empires! I want to blow up a solar system, i want to ignite a gas cloud into a new starsystem, i want to collapse a red giant into a black hole.
Think of the gameplay implications, all those redundant gas clouds in nebulae (there are SO many of them) could finally turn into something useful at the endgame.
Dont need that 54'th hydrogen cloud? Compress and ignite it with your super device to form a new star system, with random planets and goodies (lets use our long term imagination here, no reason to expect all races to operate on 24hr cycles :P)
And either collapse the red giant independent system near you to a black hole to make a research outpost, or just do it to your enemies homeworld just for lols, but beware the future as they will now have easy access to that 600% research bonus.. (possibly increase it even further for these new black holes, to incentivize investing in this mad hard to reach tech and give consequences for wiping out an enemy solar system. basically giving him huge tech bonuses)
Bottom line, i want god techs. The ultimate new tech line, call it Astro Engineering or something lol, have it suck points from High Tech, Industry, Energy and Weapons, making it progress very slowly.
The first few techs could be something like, compressing a gas cloud, just making it shrink in size (gameplaywise), later on requiring the "ignite" device.
This could all tie in with the planet destroyer "lore" =D
If the proper code for this went into the expansion (it can already be done by entering the galaxy editor, remove the gas cloud, add a new starsystem, etc, this could open up another type of galaxy for generation as well, "living" galaxy! A galaxy option that sets a random timer on all red giants, from too-long-to-ever-notice like 90 hours to something more imminent like 1 hour, where it collapses. And a possibly linked timer on some of the gas clouds, making it compress into a new starsystem as you lose the red giant, keeping the star system balance in the game so as to not have a blackout near endgame XD
Birthing and killing stars, thats what i've wanted since Spore had me hooked on their lie-hype.
