In some instances, you'd be like "who cares about silly little points?" But then, I wouldn't know how to boost up points to have yourself some bragging rights. I was chatting with mi amiga buena McLaren'sAngel about B-Spec, and as I was telling her about how this stuff is perhaps your saving grace to winning in GT. There's something you have to remember about B-Spec mode, however. You're still racing through everything. It isn't like your AI racer just goes on by itself while you kick back and talk to your girlfriend/boyfriend over the phone. I felt like a crew chief or a college football coach trying to root on my AI racer to do its (because the AI driver can be male or female) job. I still remember saying to it "come on, kid!" and "okay, you did good, kid." I think if you have leadership qualities, this mode may just be for you.
But that's real interesting to know about B-Spec mode switchovers. For the point-minded folks, just do your best in A-Spec, and if that fails, get your B-Spec points up. I never gave up when I raced. Heck, I was happy if I got 5th Place. Much better than 6th. I'm no newcomer to the GT series, and I'd feel pretty bad to get 6th all the time with a totally revised GT game.
