Gates to Another World is the sequel to Might and Magic: Secret of the Inner Sanctum. There are many improvements over the first edition of this series. Of course, the graphics and sound have been updated. Also there is a more structured story, with a plot you can actually follow. Fortunately, it's not too structured, as some RPGs have been. There is still plenty of room for you to explore and figure out what to do, and many of the quests can be completed in whatever order you decide is best.
So get ready to create your characters, build your party, and fight some nasty critters. Unravel the mystery and save the world of Cron once again.
