I bought a sealed copy of 32X NBA Jame T.E. about six years ago. Since I'm not much into collecting sealed games, I opened it up after a couple weeks, only to find that the thing didn't even work. It was just a dead cart. Worthless. I should have left it in the shrinkwrap, at least then it would have still had some sort of imaginary value.
I never bought another copy, so I can't say how good the 32X version is, but I thought the Saturn version was pretty perfect. I'm not sure I even noticed the load times, though that doesn't mean they weren't there.
