I have about 10 games on both SW Pro and DI. Maybe a little less on DI.
Quickly, SW draws you in much faster than DI (in my opinion).
It's my experience that you need 2 hours+ on JJP games to start getting the feel of them, and get your head around their "grandeur". That's why JJP games are great in a home environment. The game becomes a sustained pleasure, that burns bright, but slower.
SW was fun. It kicked me in the Jimmy right away with its theme and music, and fast balls. It was like a quickie. It left me satisfied, but I walked away from it easily too... I haven't craved its gameplay since.
Is that bad?
