Magic Duel – A free to play web browser game, that’s part RP, part PvP, part puzzle solving. You fight via creatures that you buy during the game – leveling them up to create powerful rituals to fight NPCs and other players. But the author has this system that you have to maintain a sense of balance to get the most out of your PvP wins, so you have to create rituals to lose just as often as you win, or trade wins and loses with other people. Character levels are represented by mind power, where you get to replay the game but wind up with access to more parts of the game each time.
