Well, it has a lot to do with monies. I personally have only done pros in the past, but I'm looking at a Prem for this one.
Are the "upgrades" worth 1700? Well the turntable and ramp are better for me, subway lock doesn't excite me, BUT I'm also officially out of space so I don't need as much monies to save up anymore. So I guess it is to me?
I don't think the game plays any worse, which can happen with games like GOT.
