So how come the CD version of this goes for so much? It's probably not because it's an awesome game that everyone is clamoring to get. I assume the availability wasn't very good originally or a smaller print run as opposed to the turbochip or something like that. Bonk III is sort of similar, right? I don't think the chip version is cheap or anything, but the CD version is considered the rarer or at least more valuable of the two, right? I'm just speculating, I could be wrong but thought there might be some kind of parallel with these dual format releases. I know Bonk III belongs to that 1993-TTI-is-dying club where every game released at the end of the system's US lifespan had limited production. Did I forget about any other dual format releases? That's all I can think of.
