GTA IV's storyline is such a rewarding thing to finish. Just the feeling that the whole of Liberty City is at your fingertips, and no nagging missions hanging over your head that you've yet to finish(unless it's that plagued optional street race that I can't stand). Niko's business is done, now it's time to free-roam without any guilt. Go out with a friend(NIKOOOOOO, EET EEZ YOUR CUZZIN), see the sights, go on a murderous rampage(subject west-bound in a... helicopter), subject your brain to the dozens of minutes of mind-numbing in-game television for the masochistic types out there, or jump off the GetALife building(you know you want to). You feel like a top-of-the-world badass for completing the dozens of missions needed to get Niko the vengeance he craves. You feel accomplished. It's a wonderful feeling.
Then you realize it was just a game, turn the Xbox off, and go eat some comfort food.
