I've got four daughters -- the oldest turns 12 this month, and the youngest is 5. After just a day of playing, they're entranced. I'm just wondering how long that will last.
Great intro video, and nice introduction to the pet, "hatching" it and playing games that require you to use your hands, not the Move controller. That was actually a source of frustration, as the kids wanted to use the controller (we just got them, so the new factor hasn't worn off yet) and had to be coaxed to just use their hands. Once they understood, though, they had a blast. Dress-up is a favorite.
I was frustrated by frequent and sometimes insanely long load times (five minutes, at least, once the two new pets were hatched and the initial interactions complete -- shorter if there's just one new pet being hatched, and shorter between other activities, but still a good minute or two with some regularity, though at least it has humorous load screens). Every time you switch activities, there's a load screen, and with two players they seem to be longer than with one. We've also had it appear to lock up -- no indication it was reading/writing to disk, and no response to controls (even the PS button), but that's only happened once. Still, the load times are a turnoff for a game geared towards kids with short attention spans.
I was also frustrated by the controls at times. For example, another review expressed problems with this too, so I know it's not just us: coloring your pet or its clothes are rather hit-or-miss. You can point the controller at the correct place on the screen, press the button...and nothing happens. Try ten times in a row, and maybe on the tenth try it will work. I can't figure out what the issue is, but persistence appears to be the key here. Some changes are previewed before you make them (color changes) and some apparently are not (hair style/length). The entire dress-up mechanism is likely to be a favorite (if LBP is any indication), yet it's very frustrating for kids, and I hope it's improved.
Worth mentioning is that to start with, you can see a ton of outfit pieces -- but can't try them on. You have to "buy" them with in-game currency you "earn" by playing games. That means the kid who would be content to just play dress-up with her pet and never do anything else will be forced to go try to figure out how do other things with her pet to earn more coins so she can buy more clothes to play dress-up. It's a great strategy in an adult game to get you to explore various gameplay mechanics or options, but I'm not sure I'm fond of it here. I don't want my kids to abandon the game because they can't play with it the way they want unless they do things that don't feel fun. Really, the RPG "grind" isn't necessary in a kids game like this, is it?
And if you haven't tried the EyePet demo, you should try it before you buy. As in the demo, you have to put the camera very low to the floor (within 30 inches, I think they recommend) and tilt it all the way down. You then play on the floor. It would be easier, I think, to have a large coffee table and try to use that as your playing surface -- or, get down and roll around on the floor with your kids (if your back can handle it!). That means you'll be moving your camera, as all other games recommend you have your camera immediately above or below your TV, and ours (like most, I assume) is more than 30 inches off the floor. Just be ready for it.
A lot of fun, at least at first. Annoying glitches and load times cost it a star or two, but there's a lot of potential here.
We haven't had time to explore everything - there's a fair amount of content here, much of which needs to be unlocked by earning in-game currency, so I can't evaluate it all until we play more. We played this New Year's Day 2012, so if you're reading this a few months later and I haven't followed up with an update, add a comment and I'll followup with some details on longevity.
