If you haven't picked up on it yet, the basic theme of my experience with NASCAR 21 Ignition is that it seems to float around between good and mediocre - but mostly stays in good territory when it's not having a graphical aneurysm. The only big common denominator that ever really bothered me is the bare-bones nature of it all. There's not much customization options, race modifiers, or racing modes. Even for NASCAR, it just feels a bit too simple too often.
Couple that with the mediocre graphics and no current gen features or enhancements, and it ends up being a fairly hard sell for its full price of 60 bucks. The most hardcore NASCAR fans among us will probably still get some enjoyment out of it, and it's saving grace - the racing itself - is undeniably adequate. For many, that might very well be enough. But in terms of just about everything else, it's a bit of a snooze.
