Not really. If I were to design a EULA for anything, I would obviously be very clear about what what the service was intended to provide. The central paragraph that I'd be looking at is probably KKL §16 ("Konsumentköpslagen", Law on consumer purchases), though I haven't really looked into it more than that. It's hard to argue that the game doesn't work as intended, because intended behavior is, obviously, more or less whatever we want it to be, at least we can make a pretty good case that most behaviors are intended. It's also hard to argue that anyone could be caused harm (in the legal-technical sense of the word) by a policy like ours. Also, an EULA like that would obviously make it abundantly clear that no one except us owns variable game data. Pacta sunt servanda, and all that.

EDIT: Though I won't deny that consumer purchase laws tend to admit the strangest benefits and privileges to "consumers" in civil cases. For a discussion on why the distinction between "consumers" and "producers" is arbitrary nonsense, I can only refer you to von Mises excellent critique of it. Loftar has the page numbers you'll want to take a look at.
