[Strategia_In_Ultima]

Branch out the theoretical tech starting points massively, so you can fully specialize yourself in using, say, highly advanced boarding combat where an Escort with marines could overcome a Dreadnought of standard lower-tech security stations. Also, I would like to see LOTS and LOTS and LOTS of theoretical starting points, so you can start your specialization in the beginning. Also, though I think you already got that, make the higher-lev theoreticals VERY expensive.

What I picture when I think about the finished version:

Branching tech trees that can keep you researching constantly for hundreds of game years.
Races that completely specialize themselves in certain tech areas and therefore attain unimaginably high levels in one field of research, but have excruciatingly low expertise with the other tech areas. You could specialize your race in, say, sniping, where you get to have strong, accurate, very-long-ranged weapons on relatively fast ships, and very strong CS, and many specialized Sniper Warship ship hulls, but your largest ship of the standard tech tree could only be a Destroyer.
Races that need to trade in order to survive. They have very advanced technology for, say, stellar manipulation, and can do things other races can only dream about, but they're expanding so slowly and their military is so weak that they rely on trading to make sure they don't get annihilated by a larger power - like, they need the protection of one large Empire, so they manipulate a lot in their favor, for which they receive in return military protection and the resources needed to keep their enormously expensive business going.
Racial tech areas that are even more powerful than all racial techs from the stock game combined. Genocidal Warriors could have extremely strong short-range weapons (we're talking 3-5k at a range of 6 or 7, max), virtually impenetrable armor and massive warships, but who do not get access to higher-level facilities for things like production, research, intel etc.

Please, do your best! I can't wait to see the finished version!
