It delivers exact what you expect.
Firstly JPOG (as it's commonly abbreviated) is a game that offers something that many games do not. The chance to make dinosaurs! Who wouldn't love that? Now maybe there will be a few people who don't love this game, but that's a given.
This game gives players the chance to relieve the Jurassic Park experience, to create a park on your own island and to take care of it. Exactly how you saw it in the movie, only they've added more for the game. Rides shops etc, all these little details tie in to the game to create a more impressive environment.
Normally with games that give the freedom of construction option, there are catches, glitches, problems. With this game there isn't. It's simple and it works. The level of freedom that is given is quite expansive for such a game the whole Island is yours to build on, and if you have the money, you could cover the entire island in buildings, roads and whatnot. You can even expand the dinosaur paddocks into the ocean.
The gameplay mechanics have been balanced out to give the most stable and enjoyable time while playing this game. Everything from taking care of the animals by supplying them food or giving them vaccines to feeding the visitors is all made simple through the menus that are easy to access and understand.
When things go wrong in the park the good thing is that you're alerted, even if you haven't gone through training you could still understand what to do and take that step ensuring that the park stays safe and everyone has fun.
You also have the ability to research, for a price and a certain amount of time, you could improve your park. Whether that be umbrellas for the visitors or faster dinosaur growth it still helps.
There are just so many things that you could do in the game to achieve a working park. It's your island and you're literally God. You can create pools, mountains, plant trees all sorts of things. Theres just so much put into the game its hard to get bored.
The visuals and sounds are one of the most memorable parts of the game. If you're a fan of the movies, then the game will appease you. The dinosaurs all have the same look as those from the movies. As well as the sounds. Terrifying and terrific roars fill the landscape creating the perfect Jurassic Park atmosphere. But wait theres even Jurassic Park music that will bring back even the most nostalgic memories of when you were younger.
Even so if you're not happy with the current skins you could always join the JPOG community and get some after market modifications that change certain aspects of the game.
Jurassic Park Operation Genesis is an underappreciated game that is fun no matter who you are.
