The original 'proper 3D' first-person shooter allowed you to look up for the first time. It was also scary as hell: few will forget (though many may not admit to it) wetting their pants the first time a Fiend bounded at them. But Quake's greatest legacy is its pioneering arcade-style local-network and online multiplayer modes. You will suck to the absolu e technical maximum when you start on these - Quake requires Olympic levels of practise. OMG, ur such a nOOb LOL!
