PlanetSide 2 by Sony Online Entertainment is basically the poor man's Battlefield 3, but the maps are as big as they should've been, there's more than two factions (at one time, too!), and the gunplay is more satisfying.
It originated from a snide comment a VS friend of mine made about our (the rest of us play TR) most recent victorious battle, saying something like "You talking about a biolab meatgrinder?". Somebody responded "You call it meatgrinder, we call it Tuesday." (which it was), and thus the poster came to life.
