I've long
argued that MC was the penultimate Turbochip (followed by Bonk 3).
Being one of the last ones out, it received almost no distribution (we know that the last SCD's were actually released by TZD, post-TTI).
So there was a lot of stock sitting in a warehouse. Then there was the bulldozer. I put forth the theory that TTI snatched up as many copies of Bonk 3 and Soldier Blade as they could, while the no-name third-party shooter from Quest got the shaft.
Compounding all of these problems is the fact that U.S. gamers were starved for Turbochips at the end of the Turbo's lifespan. Whatever new hucards were available went fast, giving MC a reputation for scarcity from the get-go.
