When it comes to that campaign, San Andreas is a bit less of a hassle than it used to be. It's worth noting that this is the first Xbox version of San Andreas to incorporate Achievements, so if notifications and meta-points happen to give you additional motivation, you might find additional reason to explore, experiment, and complete the campaign. Most extracurricular activities are quickly introduced and rarely overstay their welcome, save San Andreas' insistence on making CJ's health reliant on side activities like working out and visiting restaurants.
