FN FAL > M16 in Fallout Tactics
At least that. AK47 was a quite respectable gun in FOT, pretty much THE standby gun of the middle-game, excellent for fighting Beastlords and Deathclaws* until Super Mutants started showing up with their murderous big guns and their high HP and DR/DT.
FOT was also a bit bizarre because sniping was fail there. Sniper rifles and called shots sucked, the way to victory was to fire as many shots as you could - totally different from original games, where called shots were king.
*which were quite lame in FOT, for some reason. Multiplayer balance? Afraid of throwing real deaths at early game?
The problem there is even worse
There should be no FN FAL or M16 in Fallout Tactics. I would't have minded the AK47 because it was cannonical (There was a AK-112 in Fallout - It was terribad, btw. Better used for selling or kindling), but the rest simply didn't belong. When you consider all the WWI and WWII weaponry in that game, you wonder if all factions are getting their guns from museums or something. Hell, I would't mind seeing a old, pre-divergence gun pop-up - Say, hand-made post nuclear AK47 clones, the Browing HP 1911 was well-done, but the rest were bullshit.
Another problem is that most devs (esp. pre-google devs) had no grasp of guns whatsoever, so the result is that you had weirdness where a pistol >>> assault rifle. Fallout/2 is a good example of this, all the assault/battle rifles are crap inferior even to SMGs, what you want are good guns like Desert Eagle, Hunting Rife, Combat Shotty, Sniper Rifle, 14mm, .223 Pistol, etc. Remember the FN-FAL in FO2? Horribad crap gun, ammo modifier was good but the damage was wtf and it had a 10-round burst that was simply DERP. Assault Rifle was same thing. To someone who had a friend in military telling me FN-FAL was one hell of a gun, it was simply frustrating. Only Assault Rifle that was good was the H&KG11(E), and it weirdly had a SMG model AND counted as a two-handed weapon - What the fuck.
