My, how first person shooters have changed! (As seen on Reddit.)
This is true and do you know why kiddies? Because you all drool over stupid online multiplayer. In 93 multiplayer was virtually non-existant, so game developers were required to make a compelling and rich single player experience.
Now you all bitch and moan if the multiplayer isn't the best thing in the world so developers pretty much ignore the single player part of the game and work on the crappy multiplayer.
