I bought my PCFX for many of the same reasons yo mentioned about. It was my dream to own the 32bit console from NEC and spend countless hours with it just like I did(and still do) with my TurboDuo.. Well, I would have to say that is NOT the case.
I do enjoy the system, and recommend buying one, just don't expect the same typed of experience that you have shared with your Turbo. A majority of the games released are Heavy into the Japanese text. Very few releases are pick up and play. I own a couple games, and I can say that I enjoy them, but NEC went in a complete different direction when producing games for the PCFX.
I say yes, but it may collect dust~ Still cool to collect for though!:)
