This was also an attempt to add in far more variety to our game without doing any more work. In addition to customizing your face, you could now have some control over your body as well by being able to change what pieces you were wearing and color them whatever you wanted. The idea behind this was to give the player far more control over how their character looked. This was one of the first things I proposed when we started ME2 very early in production. The idea to change the way we handle the character armor was art driven.
What challenges did that present? Was the decision to go to this new approach primarily motivated by gameplay or artistic reasons? Rather than having dozens of different armor sets that Shepard can equip, he now (with the exception of the special armor sets like the Collector armor) has a base armor that can be heavily modified and is added to over time. One of the big changes with 2 is the character armor.
