There's a good chance that Firefall is going to be your absolute, undeniable jam. It's just one of those combinations of features and ideas that should apply to at least (but probably more than) one of your sensibilities: It has class-based shooting, customizable loadouts, loot, strategy, a persistent world, character creation and a focus on cooperative, Player vs. Environment gameplay.

Any of those tickle your fancy? They tickle mine. They tickle all of my fancies simultaneously.
