Bomberman, Guilty Gear, Ogre Battle.
Can't remember if Rule of Rose rocked or sucked in the end.
Bomberman is primarily developed by Hudson Soft - a few games in the series have been made by other developers. Atlus' involvement only extends to having published a small handful of them in North America.
Guilty Gear is Arc System Works. Atlus was just the North American publisher for the first game.
Ogre Battle is developed by Quest - Atlus was just the North American publisher for the PS1 port.
Rule of Rose was developed by Punchline. Once again, Atlus was just the North American publisher.
EDIT - And because people keep bringing them up:
Disgaea was made by Nippon Ichi. Demon's Souls was made by From Software. Odin Sphere was made by Vanillaware (though to be fare, several founders of Vanillaware previously worked at Atlus, where they worked on Odin Sphere's spiritual predecessor, Princess Crown). Snowboard Kids was made by Racjin (previously known as Racdym), except for the DS game, which was made by in-glove.
Atlus was just the North American publisher for all these games except the Snowboard Kids series, which Atlus publishes globally.
