I played Octoberfest at TPF and I found that to be better than any other new game at that show IMO.
I agree with the OP that at least in terms of reveal info (Wonka) Octoberfest prob a better bang for your buck for the price.
Wonka seems like a great shooter (awesome geometry) but very underwhelmed by the mechs/gimmicks. Wonka seems like a back to basics pin (like how Stern did with Iron Man - great game, but no crazy wow factor stuff). This is the first JJP game that to me, is MISSING "crazy wow factor" stuff. Every other JJP pin had cool shit, this game doesn't seem to have that. Again, underwhelmed.
