Aaaaand let's try that again.
I beg to differ, at least on the logical progression spoken here. A character in Gearhead can use pretty much any gun s/he can lift, and you can lift a limitless amount, it seems. If you don't quite grasp what I'm saying, try entering Kist at higher levels. You'll find that you can carry more than you could ever imagine, but you'll also find you can't move very well. At all.
Yes, this is quite the penalty, and I'll also say that, yes, this penalizes the relevent stat for firing small arms, but for some reason, that high-calibre minigun still hits just as often even if you've got a strength of 2. For a weapon with muzzle climb issues, like a truly automatic shotgun, strength = control. True?
