Popular Mods (SEIV)
TDM-Modpack: greatly improves the stock AI and adds several new races and fleet formations, but does not change anything else in the game (components, techs, etc.). Created and maintained by Tampa_Gamer, Daynarr, and [K126]Mephisto.
Pirates and Nomads: introduces Quasi-Newtonian Propulsion (bigger ships need more engines to move), Pirate and Nomad racial traits (they do not need colonies to survive), and a whole slew of other gizmos and racial traits. Created and maintained by Suicide_Junkie.
Proportions: an attempt at a more 'realistic' game by dramatically slowing colony development. Reproduction is dropped to 10% of normal and production on lightly-inhabited worlds is significantly dropped, while homeworld production is boosted significantly. Also introduces many new components and facilities, and balances costs for racial characteristics. Created and maintained by PvK.
Devnullmod: Introduces new components and techs, a tweaked combat system, and AI's to use the changes effectively. Also includes the infamous Space Monsters. Created by Devnullicus, maintained by Rollo.
Fyron's Quadrant Mod: Introduces many new quadrant and system types, including several that are AI-friendly. Also includes nearly 40,000 (!) system names. Created and maintained by Imperator Fyron.
There are a whole bunch of other mods out there, such as the Babylon 5 mod, the Star Trek: The Next Generation mod, and Derek's Mod, that I am just not familiar enough with to comment on. There are many more that I have forgotten about as well. If I missed your favorite mod, please don't flay me, as I am just a scatterbrain (and I've written too much tonight as it is [Razz] ).
