List of unproduced Drillimation productions

This is a complete list of Drillimation content that was canceled or unreleased due to concerns or conflicts with other content, or may be a decision by the company.

Dinosaur Rollercoaster
Dinosaur Rollercoaster was a planned arcade platformer being developed by the same team who worked on Super Smash Keyboards as they were taking a break from darker concepts. The game was originally going to be lighthearted and family-friendly. Technical difficulties caused the game to be canceled, and from a request from British game developer Rareware, the game was reworked as a serious but humorous game called To Heart.

K-On!
Drillimation was one of the various media companies who submitted bids to purchase the rights to adapt the popular yonkoma K-On! into video game form, along with Sega, Taito, and Konami. Initially, the ideas were going to be a rhythm game using the Konami Bemani engine on other Drillimation games such as Taiko Drum Master, as well as video game adaptations of the anime. However, there were disagreements over what Kakifly wanted the game to be, as Drillimation wanted to make a danmaku shooter series like Touhou Project, Lucky Star, and The Adventures of Haruhi Suzumiya. The rights to the franchise were eventually bought by Sega.
