This project was awesome to work on.  Period!  On Ghosts, I art directed 2 multiplayer maps and 3 single player missions.  I was so engrossed in the development of this game that the amount of time spent on it felt halved, seriously.  And fortunately, as a concept artist, I was able to "skip" the bug fixing and optimization period (supposedly I hear it's pretty tedious).  I'm confident Thomas Hamilton could have used my Donkey Brains on the job though. lol
