The default gun is stuff.
Woah, boy. No need to go so far. I can never agree with you that the default gun is stuff. The default gun is the way it is for a reason. This is blockland. By definition, based on the defaults:
Octagonal barrels (Gun and Rocket L)
Low poly guns (Gun and Rocket L)
Bevels (Hammer and Wrench)
Partially smooth, partially flatshaded (Gun, Player Boat, Horse, Jeep)
K.
No opinions here.
No one has to follow these rules (I don't :P) but this is the way it is.
