I had to bite on this, as I was intending to snag Forza 2 this week, anyways. I had rented it out from GameFly for a while, but never could bite on buying it. As for M:UA, I never really looked into that one. But it really looks fun, though.
With a leftover gift certificate (which I totally forgot about), ended up paying $16.30. WELL worth it at that price.
