I'm honestly very happy with this product as it gave me the chance to have a hard copy of the two expansions in Australasia.
I also saw the "following on from" part and originally thought this was an expansion, but actually did some very very quick research and found out that it wasnt.
IMO its probably a problem with the english translation on the box or something and was meant to be "following on with".
Yet saying that, i can understand if you purchased it in store on an impulse that you would trust it was an actual expansion. I was lucky enough to be familiar enough with www.galciv2.com that i knew stardock hadnt made another expansion.
Refund possible from the purchase store? Probably not, but oh well.
