The beta is pretty fun, plenty of neat things, it also has a easter eggs in it
I suck at bowling, i like the arcade games (They now have Echochrome as one of em :O), pool is fun, and going around the plaza, theater, mall and the game place (The place with bowling and stuff) with other people is pretty fun, you got people talking on their mics about stuff, you got people talking with keyboards/on-screen keyboards about stuff, you can play games with them, you can dance with them :D
As for the easter eggs, it was posted quite some time ago on the Playstation forums about some glitch that let you travel anywhere you wanted to, someone went to the pier that's outside the invisible wall in the studio place (Which is actually your own personal room), out on one of the piers is a concrete plaque that says something like "How are you seeing this?" and with that glitch someone else found some kind of trip mine (Doesn't work) from some other game, that glitch has been fixed since then, but i was trying to pile stuff up in my studio trying to break through the invisible wall, didn't work... Oh well, the beta, though glitchy is still quite fun :D
