Life's a game. How do you play?
Funny because it's true. While I do believe that every game should have a fair balancing of weapons, whatever happened to the days when developers just said "F--- it" and threw in a BFG9000 for the main character to vaporize fools with? The BioShock drill got an ammo meter, rather than the Overheat meter it was supposed to get (WTF?), the 50 Cal from CoD MW, which killed a helicopter in the campaign, doesn't kill an enemy in the first shot in Multiplayer, when in real life it leaves bowling-ball sized holes in the people it hits.
It seems that every FPS on the market is suffering from a sort of Magnum Dysfunction, where weapons that should be able to turn enemies into dust in a fight suddenly lose all pretense of combat capability in a rather embarrassing moment, when that grunt you thought would eat it after a DMR round to the head looks around, apparently as amazed that he's alive as you are, then promptly eliminates you with a plasma pistol overcharge that barely fazes an elite.
Thank you to CoD: Black Ops for including the Grim Reaper and Death Machine as care packages. This is a heads up to all other FPS makers: even if you have created such a ridiculously balanced game, there are still ways that are fun and realistic to break the balance. Got that? YOU CAN BREAK THE BALANCING IN A GAME AND NOBODY WILL HATE YOU!
