I'm very happy for you if you want clan rooms in a 3d environment. But I don't see this as a system-seller feature.
It's not about system selling features! Most 'system selling' games appeal to at most 20% of the console base. A system is bought for it's entire range of services and features. What Sony understand very well is one set of features doesn't appeal to everyone, so they're throwing in all sorts of stuff. That way the entire system appeals in different ways to different people. Think of it more like a package holiday than an arcade hall.
Mr. Blogs wants a holiday with lots of exciting activities to do
Mrs. Blogs wants a holiday with shopping and meeting new people and getting pampered
Miss. Blogs wants music and pop-culture and hanging out at the Mall
Young Master Blogs is happy to have a sandpit and adventure playground
If your holiday only caters to one or two of those people, and your rival's holiday (all other things being equal) offers them all something they want, in a well balanced household that respects everyone's interests and doesn't just do what the mum/dad wants(!), the rival's holiday is more likely to get custom.
None of those options is a 'Holiday Seller'. The holiday isn't bought for just the activities, or just the meeting people. It's bought because it enables all the different personalities in the household to get something they want from the holiday, so they'll
all enjoy it. If you create the ultimate adventure holiday, 2 months trekking across the Andes with loads of off-roading, kayaking, paragliding, etc., you'll please the Dad but everyone else in the family will whinge and moan. And that's where the hardcore gamers are looking at this from a 'what does this service get me for my $600' POV. 'All I want is adventuring, so why should this holiday company be throwing in 2 days shopping and pampering every week??' They put in the shopping and pampering because some people want it! If it was just an adventure experience, you'd alientate 80% of the world's holidayers. If you want to attract everyone, you need to offer something for everyone. You need to provide services and features that perhaps only 10% of your user-base care for, but which is super-amazing-fantabulicious for the 10% who use it. Just trying to appeal to the largest common denominator is going to
exclude a far larger percentage of potential buyers.
Or another analogy, iuf you plant a garden to attract butterflies. You can't just deck it out with one type of flower. You need to use different plants to attract different species. If you plant just Buddleia, you'll appeal to the largest amount with just one plant, but that's a small percentage of the total number of botterflies out there. Most don't care for Buddleia. If want to attract Western Tailed Blues, you need to plant peas even though no other butterflies are interested. But the only way you'll have all the butterflies in your garden is if you provide something for each of them.
