Singleplayer is great because it
 * 1) Can advance the story the way the Devs mean for it to,
 * 2) if your internet connection messes up (Or you don't have one), you can still play SP, and
 * 3) if you get bored of just going on rampages (Or getting your ass kicked) 20 games in a row, you can take a break and play singleplayer.
