I rented it from my local Blockbuster-type store back in the 90s ("Civic Video", was one of the bigger chains here in Australia back then), they had maybe 50+ Mega Drive titles at the time, was just random chance that they had that one. Not the best ever adventure RPG, but I enjoyed it as a kid and I still enjoy it now. I managed to buy it recently from a retro gaming store without too much difficulty, and there appear to be several original copies available for sale online.
