No, it won't, provided once every couple of months you run down the battery to around 20% then recharge it.

Yes, you can keep the power adapter plugged in all the time if you can. I wouldn't let the battery drain down as far as you've been letting (~10%). Keep it charged as often as possible especially during your gaming (keep it plugged in).
Edited: I guess go with Kappy's post. He's much more knowledgable than I am.

It's not a bad idea to leave it plugged in and charging while you're playing games. Your battery health is about average for a two year old MBP.
There is absolutely nothing you can do to restore life to these batteries. They age and then they die. All you can do is try to maximize its longevity by following the recommendations here:

It isn't two years old though. It's six months old. I got it new, it's just an older model.

OK then, just budget a dollar a week for battery replacement and you'll be fine.
Don't leave it plugged in 100% of the time, or even leave it unplugged but unused at 100% charge all the time - that kills them prematurely. Run it down every so often like Kappy says.

I'm not an expert on this, but I'd suggest NOT using it on battery power on something as high demand as gaming. Draining the battery very quickly because of high system demand seems more detrimental than using battery power for portable purposes (music, web browsing, email, etc).
I don't have any science to back this up, but it seems logical that over the lifetime of the battery, draining it very quickly could cause it to deteriate faster.
That's why many battery packs are charged by a "trickle charge" method as opposed to just blasting the battery with a charge as fast as possible. Should work both ways, right?
