I'm having some serious flashbacks to rifling through games in shops in the 1980s.
I was reminded in a comment on my blog of a product originally being published by FGU.
It turns out that
Fantasy Games Unlimited still sell many of their old classics like Bushido, Daredevils, Merc, Space Opera, but mainly in PDF form now (I think)
Just for bizarre nostalgia's sake, I recommend a browse through the shop:
