The Legend of Heroes: Trails of Cold Steel IV - "Cold Steel III” Costume Bundle (Only for the owners of The Legend of Heroes: Trails of Cold Steel III)

Will this still be added to my account despite not owning Cold Steel III but not usable? I plan on buying Cold Steel III at a later time on discount.

I think your best bet might be to PM a bluetext to ask about this.

I haven't bought CS4 yet but I own CS3, and as of yesterday I have a CS4 entry in my account telling me it's a DLC in need of the base game. That makes me think GOG ran some sort of script to add it for CS3 owners. Maybe they've also set things up so that it'll be automatically added with future CS3 purchases, but that's speculation on my part.
