While the Blue-Bot comes in handy for proto-typing of games very quickly, I do find myself constantly thinking how I would love real models to work with. Yes there are the Maximo models, which do come in handy, but as discussed in another thread they are using a custom skeleton rig so you cannot add new animations to them as quickly as the Blue-Bot. I am all for this, and full 3rd person model, replacement models.
Edit: Also, those guns look fantastic!
