How about the light show? That is probably another difference i assume right? None of the extra features add up value wise im sure, its just a matter of if you want the extras or not. Its like on MET, that is another strong pro model but i ended up going Premium because i wanted the spinners and the light show mainly and it also has a couple of other things like the coffin hammer and the rising cross also. Those features definitely dont add up to the 1500 extra that i spent but i still enjoy them and i will be able to do so for the rest of my life because the game is a keeper for life for me.
If the game is going to be a keeper then i would consider a Premium model but if you know that you will trade it in a few years id go with the pro for sure. Ive played the pro on GOTG and its really a great game. There is no shame in pro models like some people try to lead you to believe on here. I have a TWD Pro, AS Pro, and a GOT Pro and i love all three of those games and im not bothered by my choice at all with them. I also have a GB, MET, and IMDN all in Premium models, and out of those three only the GB is truly worth the extra money to go Premium.
