I am currently looking into purchasing one of the systems but am not sure to which one. Price is a factory and also I have a child who I think will be able to use the kinect system. But she is only two right now. I am also interested games and also great features for my system. Which one would you recommend and also which one would you recommend for kid 2 years of age?
I echo the other responses stating an iPad is a better option. There are many educational game options in the iOS App Store and the iPad is an easy interface for a toddler to learn. I know there are some that are going to say a kid does not need any of these things and should be playing with legos, blocks, etc. My son, now 4, plays with these things as well, but he also gets a little iPad/Computer time.
Now, if you want to introduce your child to game consoles, next gen may not be the right option now... I started letting my son watch me play video games at 3, but I only played specific games around him (i.e. no violence, bad language, etc.). Little Big Planet for the PS3 was a big hit. He really liked to watch the platforming elements and we even designed our own Sack Boy together. We did more of the same with Little Big Planet Karting as well. I even let him play both a bit and he wasn't bad. Especially with LBP2, I would design a very simple level for him to explore and he had a blast.
I currently have a PS4, and there isn't really a game out right now that I am completely ok with him watching. Playroom might be an option, but I don't have the camera. Maybe some of the indie games on PSN, but I have not gotten them yet.
It's not my recommendation, but If I absolutely had to pick a next gen system to play in front of my child, it would probably be the Wii U (I hesitate to call it next gen) or the Xbox One (mainly due to Zoo Tycoon and possible other Kinect/Family friendly games).
If for yourself, the XBOX One seems like the winner again this generation. The PS4 is encountering some bad hardware issues.
I'm pretty sure the Xbone issues have been more wide spread.
