Galaxy's End was to be released for the PlayStation Portable sometime in the mid to late 2000's. However, due to a variety of factors, the game was never released.
Developed by Tiki Games, Galaxy's End would have been a real time strategy RPG. Supposedly, it would take place across multiple planets on a galactic wide scale war. Not much is known about the gameplay aside from a trailer.
Unfortunately, Tiki Games could not find a publisher when the game was developed, so they instead opted to make it downloadable from the PlayStation Store. This fell through when Tiki Games lacked the budget to do so. Despite Galaxy's End seemingly being passed the Alpha-stage, the project was scrapped after this last ditch effort to distribute it.
