OMG, this game is better than Halo 3 and Gears Of War.
There is even some racing that is even better than those of Mario Kart, where you take on hillariously funny aliens, racing is intense, where you always in a head to head situation with the aliens, as it is always a close win to the finish line.
The graphics were superb, the best cell shades that I have ever seen.
So mainly, ATHF should be recommended by everyone, even if you don't have a PS2, because the game box is amazing to look at. even more fun to look at than Dragon Quest's cute Imp creatures, and Bokkun from Sonic The Hedgehog.
