Vet Emergency could fill volumes with what it lacks in gameplay. It has hardly any variety, is extremely boring, and worst of all, there's really no point to the game, at least not one that will make you want to play it. Basically, you're a vet, and you treat sick animals. Some of the greatest games are based on the simplest of premises, but this game is far from great. If games were food, this one would be a fat free potato chip. It's just not worth it.
Starting off the game will be a guided tour of the hospital. Once you've become acquainted with everything, or once the tour is over, whichever comes first, you get to work on some patients. These animals are ripe with injuries, and it's your job to help them. Not only do you physically care for them, but you must also diagnose them and prescribe the right treatments that are necessary for their survival. Electrifying gameplay, I must say. That was a joke. A real pitfall to this game is that there aren't that many patients to choose from. Each animal is quite unique, but operating on the same bruised lizard or lame dog over and over again is enough to turn off even the most hardcore of vets.
The actual process of treating your patients is not all that complicated. You have a variety of tools to choose from, and it's up to you to use them accordingly. Your choice will vary depending on the history of the patient. The real trick to winning, though, is doing everything in the right order from start to finish. This will yield the maximum amount of points in the end. It's not much of a trophy, but an actual number is better than just a 'Good Job'.
If this is all too much for you to handle, you can cool off in the game's virtual doctor's lounge, which is decorated with various posters and plants. Best of all, though, is the trivia game inside the doctor's lounge. If you really, really, really like animals and medical questions about animals, this is the right part of the game for you. The game is rife with questions you won't ever want to hear again in your life.
For a last resort, you can go look at the list of all things medical on the hospital's computer. It is basically a glossary of medical terminology and key words. It's kind of like reading the dictionary, but a lot more tiresome. I doubt anyone will ever read this, and if bytes were tangible, this chunk would be a huge paperweight.
