I agree with Carl. I got it for the season for the first time last year, and it was a waste. No Husker games IIRC, and since I had just gotten HD I really liked watching games in HD rather than the game plan games in SD.
Our early season PPV games are NOT on ESPN game plan. ESPN has nothing to do with those games.
Do you live in or near Nebraska? Then forget it. If ABC or ESPN is carrying the game, you'll see it without game plan. Game plan is mainly for regional games that you don't get locally. And if you're outside the midwest, you're probably better off spending the $20 the once or twice Nebraska might be on.
When they game plan goes HD, I'm a lot more likely to buy in. Or like Carl said, if you just want as much college football as you can get, go for it, but they were mostly second tier games I didn't care that much about. But you have the flexibility to switch out a boring game to one that looks to be closer.
