Dinosaur Adventure 3-D

Dinosaur Adventure 3-D is a 1999 educational interactive CD-ROM released by Knowledge Adventure in 1999.

Summary
The game is hosted by Rolf, a Parasaurolophus who leads the player on a journey through Paleo Island. Through an opening video, Rolf explains that a Tyrannosaurus rex has come to the island and begun terrorizing all of the dinosaurs living there; during the predator's rampage, many of the dinosaurs' eggs were abandoned during the attack and became scattered across the island (according to Rolf, this has been going on for some time). Alongside his friend Pterrance, a Pteranodon, Rolf leads the player on a quest to find nine missing eggs and bring them back to the volcano located at the center of the island, to hatch them in the nursery and use them to their advantage in ridding themselves of the T.rex.

The island is cut into three sections: the Triassic, Jurassic, and Cretaceous periods, all separated by water and/or deep gorges. The player can explore any of the three periods while Rolf will also provide some fun facts about dinosaur behavior and scientific fossil studies, including miniature videos of the dinosaurs or other giant reptiles that they encounter (three viewings of the same video provide different fun facts). Every once in a while, Pterrance will pop up and provide hints at where an egg may be hidden, and the player must use a special hunting crystal to find the egg; the player only gets three guesses, and each wrong answer lures the T.rex closer until it appears out of nowhere and attacks, leaving Rolf and Pterrance to start looking for an egg elsewhere, if the player does not get the correct answer in time. The player can only collect up to three crystals at a time, and if you find an egg and have all three crystals, then the player can bring all back to the volcano and hatch it, and then go back to looking for the other eggs.

Throughout each time period are mini-games which provide the hatching crystals necessary to hatch an egg. There are six mini-games overall, two for each time period. For each game, there are three levels to choose from: easy, medium, and hard.
