"Majin Tensei" is a strategy RPG that incorporates many elements of classic Megaten into a different genre. You must lead a party of summoned creatures to claim the victory over hostile demons who invaded a futuristic city named New Tokyo. The gameplay is round-based. You issue commands to your party, moving around the battle field, using magic or attacking your enemies physically. At that moment, a short automatic battle occurs, whose outcome is determined by character parameters. You create your hero by allocating available skill points and then improve his stats by level up.
