You begin by getting an egg from the EyePet Institute. The extra effort turns out to be worth it once you actually get into the game. Needless to say, this can be a bit challenging if you live in a small apartment.
In addition, you're supposed to clear out anything in front of the television so you have a large piece of empty floor on which to play. The game suggests that the camera should be placed at knee height, but I actually found a bit lower than that produced the best results. It took a few adjustments before I was able to get it just right.
In order to get the optimum results from EyePet you have to position the PlayStation Eye at a specific height and angle, otherwise your pet will appear to be floating in the air. Watch the EyePet Video Review right here. However, that element of realism comes with a bit of a cost in set-up time. Rather than interacting with a virtual pet in a detached way, you actually see yourself on screen with the EyePet, and while it still involves a healthy dose of suspension of disbelief, I felt more connected to this pet than I have with any of my other virtual pets. This is mostly due to EyePet's augmented reality approach. That's why EyePet was the most exciting Move game to me, and for the most part it delivers a more satisfying experience than any of the pet games I've played to date. There's just something about caring for an animal (even if it's not real) that really strikes my fancy. I've had pets of some sort my entire life, and I've been a big fan of the whole pet simulation genre of gaming.
