Originally there were gender options planned for both human and AI but that - along with the two different mech frame options - meant that there would be a LOT of combinations of options I'd have to take into account when writing.
Since I was running out of time, I figured I was going to have to cut either mech frames or gender options.
I really really REALLY wanted mech frames.
*EDIT* I tweaked the description a bit, didn't realize I'd forgotten to update it. ^^;
