Yes theres a few bugs, but ultimately a rewarding experience
The story and world which Septerra core is set in are both incredibly well written and portrayed - a definite must for any Science Fiction fans. The characters are interesting with some good dialogue between them. It's rare that a game of today took me into this world as quickly as Septerra Core has. Its a classic.
The magic/combat system is interesting and easy to understand if not quite challenging at times. Sometimes rather infuriating but with the right amount of patience pretty much everything can be overcame.
The puzzles are rather straight forward but you will find you will need to think of who you bring along to certain areas as they trigger different dialogue sequences or aspects of the game to advance.
Look out for patches, their bound to be online if you have any problems
