Imagine you’re delving into a dark labyrinth. You’re exploring the endless hallways, looking for a path leading deeper into the ruin when you’re ambushed by a dozen demons both ahead and behind. You’re certain this is the end… but then you realize your partner was trailing a ways behind you, and by now she should blasting her way through the enemies attacking from the rear. Thus assured, you unsheath your sword and charge on ahead… This is the magic of cooperative gaming.
I find it hard to get into any competitive game (with the exception of Smash Bros). The idea of playing against other people just isn’t as fun as playing alongside them. I tend to find cooperative games much more enjoyable, but it’s a much under-appreciated genre. Before the release of Half-Life, Valve promised cooperative play in the game but never delivered, instead creating only an online deathmatch mode. → Get lame or get out.
