If there is anything that can be learned from game development and the industry as a whole, it's that things change and projects come and go in an instant, and in the case of Boss Key Productions and Cliff Bleszinski, recent statements from the developer have shared some enlightening info on the constant challenges that face developers from a creative and business standpoint.

Over on Twitter, Boss Key Productions co-founder Cliff Bleszinski shared several images and bits of info regarding game concepts and ideas that were in development at Boss Key in the wake of its closure earlier this week.

After formally announcing the closure of the studio that he helped to co-found, Bleszinski was candid in sharing several game ideas and concepts that were worked on and pitched to publishers, or ideas that were still at their very beginning internally within the studio and just starting to get fleshed out creatively.

One of these concepts was for a game concept in development called "DragonFlies," which would have involved "ninja/samurai in airships riding dragons fighting zombies with friends" set in a "PVE 'feudalpunk'" environment. The game itself itself would have revolved heavily around players raising and training a dragon companion from hatchling to maturity, and would also have included a narrative-driven campaign.

This title, however, was estimated and pitched at a production budget of $40 million, where publishers such as Microsoft, Sony, EA, 2K, Activision, and Warner Bros. all passed on the project, according to Bleszinski.

Another title that he shared concepts and artwork for was codenamed "Rover" (later known as "DogWalkers"), which was a VR-planned project that would have players controlling and operating massive mechanical tank-like weapons co-operatively. Bleszinski referenced titles such as World of Tanks and Tokyo Wars, where players would have had to co-operate and fulfill different roles within operating the massive tank-like weapons.

Breaking from the look of the previous two titles, Bleszinski also shared art and concepts for a game called "Donuts" which would have been "a VR spiritual sequel to Toobin," and which Bleszinski described as "Mario Kart on water with animals in VR."
