IJ game play is much deeper and harder to complete all the modes than SS. I had a PERFECT restored SS back in '04 and sold it since it was just too easy. Don't get me wrong, I LOVE the theme and call outs etc....it was done perfectly, but it is just too damn easy to get to the stiff o meter. Granted I never finished the spider wheel which is much harder to do, but overall it's just not a pin that I could keep with only four back then. I would like to have another one, but not for the money they are going for....just isn't worth that. That being said, I had two Indy's. I sold the first back in '02 and missed it so I bought another one in '04 and restored it. I loved it but started to not play it much any more and ended up selling it to pay for granite in the kitchen for the wife. Do I miss it.....sometimes, but even when I am at other peoples houses with an Indy, I don't really feel like I HAVE to play it. I think I'm just really burnt out on all the "A" titles out there. Anyway....with a gun to my head....definitely IJ over SS.
