Still, there are a few things getting in the way of the plaintiffs being successful here. For starters, games and in-game content are often cancelled - an unfortunate reality of the industry. Furthermore, even if refunds weren't granted, Aspyr did offer affected fans a copy of KOTOR 2 on Steam - where the mod can be played for free - or another Star Wars game altogether.
How is this relevant in any way?
I don't think they're legally entitled to a refund for buying a game with content that didn't exist, but neither of those are even sort of substitutes for the content or a refund.
