* DuelingWorks: Odd to think that only a few months passed between ''Iron Brigade'' and ''Videogame/OrcsMustDie''. Both releasing on XBLA originally, and both being third-person shooters with heavy TowerDefense influences. Unfortunately for Double Fine the latter was much more successful with (currently) four titles released.
* WhatCouldHaveBeen: The original concept prototype of the game was a tongue-in-cheek SteamPunk setting, in which the player's "mobile factory" defended a stationary "steam factory" by producing a variety of crazy contraptions. The enemies attacking were clockwork automatons which were destroyed in a previous RobotWar, only to be possessed by evil spirits and come back as [[NinjaPirateZombieRobot Steam-powered Zombie Clockwork Robots]] which could only come out at night. Since a massive explosion in that war put the Earth into a rapid spin, day and night cycled very quickly, thus justifying the downtime the player gets between waves of attackers.
