You could go with you mates to a go-karting centre or a virtual track day. It could be free due to advertising on track side or decals on cars.
Real Cinema
Imagine a film's out in the cinema and you can't make it. Buy a ticket and watch it at Home. But the films need to be in Home at the same time as the cinema, otherwise you could just buy the DVD.
Animated Decorations
Such as a Transformer in your Home space. Interact and it changes from car to robot. Cool? Definitely.
Sports
Bowling is alright. But wouldn't you prefer to go with your mates to play football, rugby, tennis, swimming? Just one thing needed. Private rooms, I don't want to have to share or wait for half an hour.
Transport
Skateboards, scooters and roller blades. Three ways to make moving in Home more entertaining.
Paintballing
Paint your mates like rainbows in a forest. Would work equally well as a first or third person. A great laugh and exciting.
Music
You've got the tracks on the PS3. Why not use them? Carry a Walkman around and listen to your tracks when you want to.
Toys
Toys for adults and kids to mess around with eg. remote controlled helicopters and cars.
Building
With Home's new physics engine my sofa fort keeps falling over. Why not have a building tool similar to Sims? Build your own rooms and roofs. Sony could still sell other houses by increasing the plot size.
Day and Night
What is the point in lights if there is only day? Put night in the game and have late night events.
Art
Let's face it, chairs and tables aren't interesting to look at. But imagine that when you complete a game you get a poster or object for it. Make you Home look good and show off your skills.
TV
Same as the music. Share your movies with friends.
Wallpaper
Boring preset wallpaper is well... boring. Let me make custom wallpaper. Many ways to do this. Upload an image, an image creator similar to guitar hero (preset shapes) or go complete freedom (issues with censorship).
Proper Design
Let me make my house like Fallout 3. I don't want to have to pay £4 for a new house. Jut let me stick a M.I.R.V. by the door and gain instant respect. We need more decoration and less new houses.
Cool Areas
Imagine a jungle where you get a map and compass. Lots of objects and villages are hidden in the jungle. It would be awesome to go exploring with friends.
Instruments
You've bought the GH (or Rockband) games and tracks, so let's play them in Home. There could be a virtual jam space or private gigs to show your skills.
Sporting Events
Go to stadium, grab seat and watch a match. Simple concept? Imagine if it's linked to real video games. No need to wait until tomorrow to find out how you mate's doing. Go to the stadium and be a spectator in the crowd. This would involve a lot of work from Sony, but would give it a massive edge against XBL. Possible links EA Sports, 2K Sports or even Everybody's Golf : )
More FREE Stuff
I'm not loaded. Learn that. More Minis are sold than Ferraris beacuse they are affordable.
