I saw Rastan in a few arcades back then. It's OK, rather generic. I think it was only made because barbarian movies were popular at the time. I think it's funny that the sequel is called Nastar, which is just Rastan spelled backwards.
There is one Rastan-like game from Taito that I really liked in arcades, but I don't think it was on any of the Taito collections. It was called Cadash and it was a 2-D platformer like Rastan, but it had RPG elements. You could pick from four characters (like a ninja or wizard) and you could level up and get passwords to start up from where you left off. As a kid, I always wished it would have a home console release, and it did on the TG-16, which I didn't have. So that was a bit disappointing.
