IF you live in GA, and you are a Comcast digital cable subscriber, you can order the game as a pay-per-view for $29.95. The key word is, digital cable. This applies to Comcast subscribers and select Comcast digital cable partner subscribers, such as Charter in most areas.
IF you live in GA, and you are not a digital cable subscriber, you will not be able to view the GSU game live. This goes for Comcast's non-digital cable subscribers, satellite customers (Dish or DirecTv) and cable carriers that are not partnered with Comcast (probably few, if any of these). The GSU game will be blacked out in the state of GA on ESPN GamePlan. ESPN GamePlan is NOT the same thing as Comcast pay-per-view.
If you live outside of GA, you can order ESPN GamePlan for the weekend at $21.95 (or for the season at $99), and watch the GSU game live as part of that package. This goes for cable customers (whose cable company offers GamePlan, which would be most) and customers of both Dish and DirecTv.
