So... the Steam version is also basically GOTY?
From what I gather
on 1C's website, the standard version of Crossworlds requires Armored Princess to also be installed.
If that's true, then Steam offering The Legend, Armored Princess, and Crossworlds in their Platinum Edition is misleading because they're selling 2 games not 3, but one of them is being sold twice when you only really need the one version that has more content.
EDIT: I asked on GOG, and a mod there seems to think AP needs to be installed for Steam's copy of Crossworlds to work.
What confuses me is that most expansions on Steam have this:
or similar, while Crossworlds does not say this on its store page. Also, I'm reading from multiple sources that Armored Princess
is required, and yet Kuro tells me it's not.
