Build THE park.
The game runs just like a regular park management, game, particullarly like Zoo Tycoon. You build facilities, fences, put some dinossaurs on them and watch the cash flown in. This is the basics, but there's so much more to the game.
Graphics are beautifull specially the dinossaurs, sound is in great part taken from the movies (I just love that T-Rex seismic roar!).
You have to keep visitors happy by building all the facilities they need, setting adequate prices, keeping the park clean, and, of extreme importance, keeping them safe!
There several security options, from dinossaur repelents to auto-turrets that kill rampaging dinossaurs. Of course the best solution is, if possible, immediately tranquilizing the beast and getting it back to its fence unarmed.
You don't just generate dinossaurs from nothingness, you must dig throughout the world for fossiles and then extract DNA from them. Once you 50% DNA you can breed the dinossaur, but the more complete it is, the longer the dinossaur will live.
There many more gameplay complexities waiting for you, I would loose a day here trying to get them all out.
Just one thing bothers me, occasionally a twister will hit the island, destroying and killing everything in its path. I think the catastrophous effects of this are exagerated. If you don't have a lot of funds on hand, you won't be able to repair you're park, repairing the park is very hard gameplay-wise, you have to go through all of the damage reports one-by-one and order every single repair. If three buildings are damaged its OK. Once there are 60 things get complicated!!!
Nevertheless, the game is an exccelent and soothing experience. Sometimes its fun just too watch the dinossaurs, their AI is amazing for the most part.
Play it!
