GGGGGAAAAAAAHHHHHHHHHH I accidentally closed out so I'm typing this again....

Oh well
While bearing in mind the "forever '50s" feel and realizing the futuristic weapons seem to begin where the early AR-style weapons end, I would like to see one or two classic long guns like the Mosin Nagant 91/30 with bayonet. That would make for a great strategic change if they could implement a melee command for that specific gun (or any others that would serve similar dual purposes). They wouldn't have to get as realistic as offering up a new ammo type as well (the Mosin is an odd 7.62x54r, or Rimmed) because I think .308 would suffice.
It would also be fresh/comical if the courier stumbled upon a museum of sorts and could find such items as a mace, a crossbow or longbow, maybe a lance, and some chainmail. I'm not really a medieval Oblivion-type RPG fan, but in the spirit of fun I could dig that especially if the "knight" whipped out a 9mm at any given moment

Also, for some reason, a really powerful .50+ muzzleloader sounds like it would be a BLAST...better take that quick reload perk!
