For real though. I went to check & see how much a copy of Metal Warriors on the SNES was going for, and the cheapest BIN is $175 with a ratty label.
It's sucked for a long time, but now it's getting really f*cking ridiculous.
Anyway, best of luck on your search for Blackthorne. Looks fun, but alas, I've not the money nor the interest to shell out for a copy.
