Video game series which need another installment

[Enderwoman]

Rhythm Thief and the Emperor's Treasure. Its a fairly recent title for the 3DS, and I loved it alot. Judging by the title, its a Rhythm game, and I loved it. It had a few quirks which annoyed me a bit, but I still adore it, and it could only get better.

However, due to Sega's incompetent marketing for anything that isn't Sonic, it sold poorly, and now I will never get a sequel.
