Oh man, who remembers the original "Call of Duty" game - going back to 2003 (I think) when it was first released? That was awesome. I particularly remember playing it online. You didn't need the DVD or anything, just connect to the internet and play. It was awesome. It was basically Death Matches, like an improved version of Counter Strike. I remember 2 teams used to start on opposite sides of the map in a WW2 setting and just take your positions, camping, throwing frags, waiting for some unlucky idiot to run into open space and get absolutely peppered with bullets
And when your player gets killed, it'll show you a replay of last 5 or so seconds of the player who killed you leading up to your death. Then while you waited for the game to finish, you can either spawn as a ghost and travel freely throughout the map or follow someone still currently playing.
I also remember when you killed some, it used to say "You killed <player name here>" - and someone I killed once was called "your own mother" so the full quote said "You killed your own mother"
Good times.
