- LSR3 would have a Tower of Illusion
- LSR4 would be an RPG focusing on what Shinica imagines the Apocalyptic Towers' apocalypse to be like
- LSR5 focuses on Anegio's Castle Oblivion, revealing more of Shinica's past (like how she ended up with the Flamberges on the day she was born), with a true final boss existing as well
- LSR5 has a card collection side-quest, for a post-game bonus boss
... Yeeeeahhh... that's a lotta stuff.
