Meh. I thought the first Wal-Mart three pack released two years ago (Ford Racing 2, Corvette, Super Trucks Racing) was pretty decent - Super Trucks Racing was pretty boring, but I spent more time with Corvette and Ford Racing 2 than I thought I would. Both games are among some of the most solid budget racers I've played (along with Ford Racing 3 and Ford Mustang: The Legend Lives) and I'd say they are worth the few bucks they go for.
Another thing: these Wal-Mart 3-packs used to be ten bucks. Three extra dollars, while still a deal compared to the $10 they go for alone at other stores such as Best Buy, makes this less tempting.
I'll probably check out Suzuki TT when it drops to $5 used like games in these bundles usually do. I was interested in DT Racer when it first came out, but I've read way too many bad reviews and the time I'd waste playing it would probably be better spent on some of the other racing games in my backlog.
Thanks anyways, OP. I was wondering which games Wal-Mart would include in their next 3-pack.
