Research mods?

I'm just after any mods that add new research items because I usually have aquired most of them half way through a game, leaving me nothing to strive for apart from killing the enemy.

I guess after playing EVE I'm a bit spoilt with the amount of research items available aswell as the market, genetic modificatons and so on.

IMO this game needs many many more research items and a market would be nice too when I say market I mean a real trade system instead of just building a trade post (ala age of empires)

For instance you could manufacture goods and buy/sell them etc, I know that would be hard to implement but I'm just throwing it out there.

Also you could have a whole string of genetic modifications  for research items, that modifies your whole race, again just throwing it out there.
