i also think the m90 shotgun from (halo 2), is a rather unimpressive weapon.
it's an 8 gauge 12 round gun, it should be at least a 12 gauge 8 round gun,
as a shotgun it should give a feeling of immence power,
and cause huge damage, instead it focuses too much on ammo.
The shotgun was just fine. You just need to use it tactically and up close. If you're not close enough to shoot and then hit them with the butt of the gun, then switch to a different weapon and shoot them in the face. Either way is death.
The plasma pistol is only good for one thing, and that is to charge it up and destroy the other person's shield. Pair it with a battle rifle or a magnum shot to the head and death.
The legendary axe from donating to the temple of light in Fable 2 is terrible. Also many weapons in Fallout 3 suck major, its better just to use the chinese assault rifle. (f.e. plasma rifle/gun, most special weapons, anything melee or close ranged)
The fireflower from Super Mario Land was made of fail, at least until you got to a level that isn't out in the open. It was semi-useful shootig some flying badguys, or for getting some gold coins that you're too lazy to jump up and touch, but otherwise, it was too goddamn frustrating for words: it would just sort of bounce up-down, up-down until it disappeared from the screen.
And the only weapon from Kabuki Quantum Fighter was hair. Like, your character would have to hit his enemies with his (luscious) long hair. THAT got old pretty fast.
