This is one of the few light gun shooters on the SNES. Gt an amusing graphical style at least. Never played this one myself, so I may as well just quote the article:
"The Wild West is a woefully under-utilized setting in videogames. From Nintendo's Sheriff to Red Dead Redemption, not a whole lot of games have explored the themes and locales of the American West. Even fewer games have innovated on the genre's tropes. Instead, they crib from classic westerns and hodgepodge them into a potentially cohesive plot. Tinstar represents one of the few games about the Wild West that charts its own course."
