It makes defenses defend the run better. One of the major complaints about NCAA Football 08 on Original Xbox when compared to 07 was that defenders sometimes took odd angles when pursuing a ball carrier. Turning on auto strafe alleviates this to an extent as you will see defenders strafe instead of just taking the awkward angle. This also makes it easier for you to bring down CPU defenders in open space. You can still use the strafe button yourself, but CPU defenders will auto strafe, cornering ball carriers.
Admittedly, NCAA Football 08 on Original XBox did have its share of bugs. It's far from a perfect game. You can balance the game to an extent through sliders. Some penalty sliders work, a few had some bugs.
With the right settings, 08 on Original Xbox is the best football game ever made if you can get past the bugs. It's simply fun as heck to play. What I really like in 08 are the playbooks and the improved lateral button. The option is spectacular in 08 on Original XBox. I recommend classic camera.
People say the pursuit angles were a problem in 08. They definitely took better angles in 07 no question. But in 08 I look at it like the defenses are just more aggressive. If you play a zone, the defender will stay in that zone and wrap of the ball carrier most of the time. To be a master at 08 on Original Xbox on Heisman or All American, you must use manual control on defense. You can get buy against the bad teams by calling plays, but against a good CPU team on heisman with fair sliders, it's going to be tough. You're going to be in a battle. Every down is hard. 3rd downs the CPU converts a lot. You gotta be strong minded. If you get 08 on Original Xbox, realize that you have a great rare game that has got mixed reviews. Seriously take this advice:
Go into 08 on Original XBox with an open mind. Try to find some unique sliders. Play on all american or heisman. If heisman is too fast, do all american. use qb avoidance in college football. use receiver direct and tell him where to go then throw it. it's the last great college football game as far as i am concerned. i need to give 07 another look too.
