Less of a game, more of a virtual community geared for gamers.
Its an online community of gamers and PS3 enthusiasts.
It lacks the organization of an online message board, and the aproachability of a chat room, but allows you to roam this virtual world with a fully customizable avatar.
Unfortunately for some, its hard to strike up a conversation with anyone if you're wearing simple default clothing.
Thus the newbies are introduced to the community mechanics of "home".
I doubt the developers intended it to be this way, or maybe they did and thats why you have to pay real money for your avatar's clothes.
Back to the newbie situation...
Maybe nerds log into home to annoy and troll other people who quite possibly take Home too seriously. And said nerds (a.k.a. noobs), don't spend their money on virtual clothing for their avatar. They stick with the default looks.
So 90% of the time, any well meaning newbie in a default look will get the cold shoulder from the more interesting looking crowd.
Maybe you noticed Luke Skywalker dancing alongside Isaac Clarke from Dead Space. Or you see your favorite characters from Street Fighter 4 chatting it up with the cast of Tekken 6.
These are common sights in Playstation Home.
I still can't get used to seeing stormtroopers harassing an alien from AVP.
Then there is the middle ground, the people who buy the fashionable yet plausible clothing for their avatars.
A nice leather jacket here, some wicked jeans there, and pretty soon they form their own style. And subsequently, their own unique online persona.
By the time someone invests enough into Home and their avatar, they're probably already addicted. And most likely know the ins and outs of the Playstation Home community mechanics.
Want a "game" that never ends? Where you can interact with real people in fantastic enviroments without the constraints of a video game's push to a predefined goal, or its restrictive objectivity? Then put off buying that DLC, put aside $5 for a decent wardrobe in Home and jump right in.
I've made at least three really good friends on home that have become more than just a virtual chat buddy. These people know me and I know them, of course I've been playing home for about 3 years.
I've known these people about that long.
And I consider them as much my friends as people who've gone through school with me.
So I guess Home can be a place just like where you met your last best friend.
Its definately not for everyone, and seems rightly purposeless at first...
But say your best friend moves away, he has a PS3 and so do you, why not meet on Home. Its a cut above a phone call and more personal than a text message. Its cool, its frivlous and fun.
Thats just ONE of the reasons you might have for using Home.
Give Home a chance, between MW2 and LittleBigPlanet... try out Playstation Home. Its 20% wish fulfillment, 30% riddiculous, 50% addicting, and 100% fun.
