Well, the Little Big Planet looks cool--- for a tech demo (but is it too far to say it won't be released on the 360 and/or PC as well?). And Playstation Home appears to be a gigantic commercial for Sony sponsors--- that you have to pay to take part in (i.e. buy Nike gear, watch Taco Bell ads, pay for good backyard view, etc.). Um, no thanks.
I hate people who compare it to Second Life. In SL you can at least create your own things, and sell them for in-game currency. I see nothing about an in-game scripting engine for PSHome.
I was initially excited about these two things, but the novelty has already worn off. I'm glad Sony has something they can use to differentiate themselves from Miis and Xbox Live, but I hate the fact that nobody is talking about the PS3 games that are coming out. The buzz is on these two products that, well--- so far will appeal to casual gamers but not sell a $650 system to the average casual gamer.
