I haven't been on yet cuz I just got home from class, but I will be checking it out soon. I seen lots of videos and podcasts showing it all so I know what to expect. There are lots of free virtual items available and I am about to post several codes for them.
Bootleggers looks fun in the Action District and the emotes for Poker are very realistic. The RC racing game looks fun too. I've already seen the Hub before, but now you can enter many of the stores and walk around instead of just seeing the PS Store pages. Pier park is cool with the ferris wheel and the Theater is HUGE! I wish they didn't take listen@home away cuz now we can't select our own music, but the music they play at the Hub is very good - a good mix of modern songs.
