On Star Trek TOS, you will see a complete mod from the Kirk era made with the stuff from Star Fleet Command TOS mod and many more new things. Thanks to all these creators, this mod will be finished very fast and with great quality. At a first place the mod will add only space combat but for a non too far future, I wait add ground units.
With a few changes, this will be the units from the mod, most of the D2 pack from Rick Nox aka Pheunomic81 and Thexder "Atrahasis" Bayes and most of the models made by the TOS mod team, both made for Star Fleet Command III.
Where's the Galaxy class?
Galaxy class is a starship from TNG era, at a first version, I will not add the TNG. TNG is very advanced in time and it would need a bigger galaxy map and a lot of work more for to be a mod made at few time.
Sorry, I'm not that familiar with Star Trek eras
are you adding the yorktown class?
