How long? Probably I never will... keep in mind these are data files I've worked on a bit, held onto for months while worked on other things, worked on a bit again...

Probably if I ever finish it it will be a mod for SE5 or even SE6
OK, a summary of this mod? How about this:
The Antares Mod is a work-in-progress mod which attempts to convert the game mechanics of Master of Orion II to Space Empires IV. Features will include a completely redesigned tech tree based on the MOO2 tech tree, quasi-Newtonian propulsion, scale mounts for special (i.e. non-weapon) ship components, "structural integrity fields" a la Star Trek Mod which function as leaky armor (simulating MOO2's "structural hitpoints"), a variety of specialized mounts for use on weapons, miniaturizing technology (as you research advances on a technology, instead of it getting more powerful, it gets smaller and cheaper like in MOO2; you must research a new technology to get more powerful items), Antaran attackers based on Devnull's space monsters, and more!
edit: added reference to Antarans
