BITD, I always wanted "arcade perfect" ports; it was the holy grail of home gaming.
Today, I appreciate the ports a lot more, and in some cases, prefer them over the originals. One of these cases is Ghouls and Ghosts on the Genesis, a game I mastered as a teenager, and even though I have it in arcade perfect form in Capcom generations, I'd still rather play in the Genesis. This is part of the reason why I'm not THAT interested in trying out the SGX version. (as a side note, I also much prefer the PCE version of Image Fight over the arcade/Saturn version)
In any case, nothing you guys are saying is convincing me to buy a SGX, let alone TWO SGXs. If Granzort is the best thing going for it, and Youtube, which never lies, makes it look very ho hum, there is no reason to own one.
