Because I'm batman!

dodgy publisher rights, the original game has a store page and all the achievements, but the gold edition has neither

Strange, yet Gold suggests it's the superior Edition...

No store page because this is the same game as Commander: Conquest of the Americas but with all the dlc

Erlier it was Gold, now it is Complete Pack, that's why

I have the Gold version, yet steam does not acknowledge a Gold version here. It also does not acknowledge that i ahve the game either. Its in my games list as gold edition but everything about it does not show up, always saying i dont have it or any DLC's.

They should at least mark this up as owned if ones has the Gold Edition, instead of changing the name so it at least shows in the steam store that you own it and whatever DLC's it had. Or are they hoping you buy it again before realizing you had that or the DLC's?

That is odd

Am I right in saying the only difference between this and the other version + DLC is.. that is a different publisher and has achievements?
