People drive themselves crazy with comparisons like this. If one is in clearly better shape than the other, keep it. If not, the extra features on the remake might make me lean towards that. If you still can't decide, put em both up for sale and keep the one that doesnt go!
As far as the remake's board issue, I like B/W games because I do most of the work on them myself. But I am sure that board availability be be fine in the future. There are too many MM's, AFM's, and MB's out there for CGC to just walk away from the money by no longer supporting them, and if they do, someone else will come along with a repro, just like Rottendog, Ni-Wumph, and the guys who make the Prism board for RFM which was said to be the doom of all of those games. As far as original vs remake, JJP releases a new version of WOZ every few months. Are they "remakes"? Newer is almst always better, with improvements in technology, etc. I drive a newer Corvette which I guess could be considered loosely as a remake of earlier Corvettes from the '60's that we drove when I was a kid. You know what? The new one is more reliable, handles better, brakes quicker, and is way faster than most of the older muscle cars! When I talked to the local Corvette shop about maybe a '68 or '69 big block, his first words were -"You don't plan to drive this every day do you? This is not an everyday driver!" The original is nice, and I would love to own one. But the "remake" is just a way better deal all around, for my money.
