I would like to see the a sequel that allows you to hire session musicians, sound engineers, light engineers, choose your style of music and original music composed by artists for the game. Being able to play the song as well (à la rockband/guitar hero/fretsonfire) would be a nice bonues aswell.
It would be nice to implement patrol patterns, rather than have the guards walking aimlessly. Another addition would be the guards hearing you and turning in your general direction (when sprinting). Also, more advanced guards that could spot you when invisible.
to get the super upgrade you have to have the whole alphabet twice [you get a new hat, an other hat] you also need every single other upgrade and 1,000,000,000 $
this takes so long to do its not even funny
was listening to some good music on itunes when all of a sudden, load screen music :E
load screen music, for not having the capabilities to be disabled, i hate you.
