Get the FX 3 version while you can! With the new pack, all you really get is slightly better graphics, provided you have a strong enough GPU. Even that is questionable. The lighting is too dark in my opinion. The new White Water table doesn't even have fur on Bigfoot like in the physical version.
I'll be honest and say that I really only bought this pack because White Water is my favorite table on FX3, and I was curious how it had been remade. I have only played that table in this pack, but the gameplay is not good. In this version I can now barely launch the ball into Insanity Falls and the whirlpool. The table sounds and music sound worse believe it or not. Maybe they were trying to emulate actuall pinball table speakers, but that form of realism is not beneficial in my view.
