It's good fun, though--Trickle can dish out a lot of punishment too, and when an enemy car finally gives up the ghost, it rockets into the air with a huge explosion, ala the Burnout games. The trick is to watch your damage meter carefully and time your pit stops accordingly, so that you don't give up too much ground.
Another nifty addition is the famed "drop the hammer" move, which basically works like a supercharged nitro boost. If you drift behind an opponent for long enough, a hammer icon will pop up on the right side of the screen. Touching it gooses your car forward with tremendous force for about two seconds--it's usually enough to put you in first place, while flattening every other can you run into.
Days Of Thunder should be out sometime next week. We have no information on the price at this time.
