conf, were you around in Home when Xi was going on? That was a lot of fun and was the reason to check out Home in its early days. I participated a fair amount and managed to get all the puzzles and rewards done (with some walkthrough help, because I was not interacting with the community to do it--a necessity for certain aspects).
I was away from Home from April last year until a few days ago. It's changed a lot since then, much bigger now. I found the Xi Museum and replayed some of the activities I had done 2+ years ago. :) Interestingly, one of the old Xi spaces is now offered for sale as a personal space for $5, but because I've had it in my Favorites since 2009, I have it for free. :D It doesn't show up as a personal space, but I can still decorate it and have it save the layout.
Why Cubixx not Soccer Bashi that makes me a sad panda bear
I think the answer to this question is simple: Laughing Jackal wanted to do a PS3 enhancement of Cubixx, while Icon Games has not, as far as I know, expressed any interest in publishing on the HD consoles (they do have at least 2 PSV projects in the works, though).
