Quoted from Frax:I'm waffling hardcore between a pro and a premium. Money isn't a big concern, though I admit it'd be nice to keep the 2500 bucks or whatever and put that toward my savings for a house down payment or increase the emergency fund.
I've played them both a fair amount and own a premium. Overall Godzilla is just such a great game that both versions are a lot of fun. Still the Bridge, the building and the MechaGodzilla make enough of a difference in my opinion that the Premium is probably worth the extra money, if you can afford it. If you play both a lot, you'd probably be happier with the Premium in the long run. If you've mainly played the Pro, you will undoubtedly be happy with it as well. Good luck with your decision!
