As far as I know, Sin Mark isn't a game that CA are focusing back then. Such as Juggerdome, the game's storyline isn't good and incomplete. Its has less in details and it only takes and hour to finish the game. I hope that CA will make a sequel with more stages and proper storyline when they are done with DZ. The ending when you kill the Dragon is quite dissapointing.
Tell me your views about this game!
