RARELY DOES A GAME COME ALONG THAT HAS  IT ALL!  LOTS OF ACTION, COOL DINOSAURS TO ANNIHILATE, NOT TOO HARD PUZZLES , AND LOTS OF FUN PLAYING IN GENERAL..AND A VERY GOOD PLAYSTATION TITLE TO BOOT!!I LOVED PLAYING THIS GAME A LOT , AND EQUALLY LOVED '' DINO CRISIS 2 '' AS WELL! LET'S HOPE THEY PUT OUT ANOTHER TITLE FOR PS 2 IN THE FUTURE .AND THAT IS AS GOOD IN ACTION AS THIS ONE , AND LOTS OF COOL DINOS LIKE THE SECOND ONE.THAT WAS THE ONLY FLAW WITH THIS GAME , NOT A GREAT AMOUNT OF DINOSAURS TO WIPE OUT .BUT THE ONES THEY HAD WERE COOL TO FIGHT .. TREX IS COOL , BUT I'M AGREEING WITH MY WIFE -'' RAPTORS '' RULE!!SO IF YOU ARE BORED , NEW TO PLAYSTATION , OR WANT A NEW RARE COOL OLD GAME TO PLAY.THEN LOOK NO FURTHER..GET IT TODAY!!!BUT I SUGGEST YOU GET THE GUIDE , AS IT IS A BIG HELP IN DIFFICULT AREAS ..PLAY ON- AND PLAY PLAYSTATION!!
