I'm wondering how many copies of Rage they have, and how many they've sold during this sale. I've been checking back for the past three days, hoping to find Driver SF back in stock, with no luck so far. Each time, I've checked on Rage (360 Version) as well, and I haven't seen it OoS yet. Great news for people that want Rage, but they must have had a crazy number of copies of it to start with.
If you want Driver SF, Wal-Mart has it as part of their buy 2 for $30 get one free Xbox 360 games. The total price comes to $35 once everything is taxed and shipped. If you don't want any of the other games they offer, you could just flip them on eBay and make $28 or so of that money back. I ended up keeping Driver SF and am in the process of selling off the other 2 games I got from the bundle because they were Platinum Hits and I'm picky, so I'll use the $$ to buy back versions that aren't.
As far as Driver itself goes, I like the game. The controls are touchy and the cars all fishtail a LOT, though. There is a story, but it's stupid and not really worth paying attention to. Think of it as a collection of driving mini-games, because that's basically what it is. Being "shifted" out of your car after doing a Tanner mission and having to do some other seemingly irrelevant story mission to unlock the next Tanner mission really breaks up any continuity the game could hope to have. It seems like they did this to give the story mode sense of length that just isn't there. But yeah, sometimes the driving mini-games get repetitive, some seem meaningless or annoying, but overall it's fun and for sure worth the $8-$12 bucks.
