Oh yeah, and please NEVER EVER EVER EVER EVER EVER EVER EVER(Oh yeah, did I mention EVER?) post gun ideas. It just doesn't fit. If you're arguing; "Well I think there should be guns!", download a few mods. There are more gun mods out there than the USA debt to China. At least nearly.
Well, there's the Musket Suggestion.
As for the O.P, IDEA FARMING IS NOT ALLOWED. PLEASE FARM YOUR IDEAS IN YOUR BRAIN. NOT SOMEBODY ELSE'S BRAIN.
When posting ideas, you are required to include enough information to provide for a valid discussion. This suggestion is overly vague, since it does not provide any specific information other than the types of weapons being suggested.
