As you will recall, a Rockstar Games spokesperson gave us a rough estimate of about 100 hours in order to finish Grand Theft Auto 4. However, at that time, it wasn't confirmed whether that was just for the single-player campaign alone or not.

Now if it's still lingering at the back of your mind, Rockstar senior developer Jeronimo Barrerra has this to say about this source of itch: "It takes testers playing 4 hours a day, a good 2 weeks to get through the whole single-player game."

Doing the math, that's about forty hours of dedicated gaming for the single-player mode alone. We're not even talking about side quests yet. So the 100-hour game length remains a possibility. And mind you, forty hours is not a mere walk in the park. That's a lot of gameplay right there.

But really now, it's up to you if you're in for a Guinness speed-finish or a slow, Zen-like game experience. Now that the fourth trailer is up, it really is just a matter of time before Grand Theft Auto IV hits the shelves this April 29 for the Sony Playstation 3 and the Microsoft Xbox 360.
