What can I say excepts that a mod being developped for a decade sure must have some interest ! The development of the game mechanics is enormous ! It sure is more complex but still on it lies on the same basics, so it is still Homeword 2 and I dare say a more logical one as certain units finally get their real use corresponding to their phusical assets and possibilities when you looked at them closely in the original game...
Many of the mod ideas were taken from the original development team so it garranties the quality and the credibility for the Mod to definately be a Homeworld one. Ice on the cake, the Mod leader has been included in the Homworld Remastered Dev team, so it garantees continuity with the future modding possibilities of the Remastered version.

And if the original game dev team was so breathtaken by the Mod team's work, there is a good reason for it, that means that the Mod shared their ideas !
