This past E3 has been by far the most boring for me.  Sure they showed off some great games, but the amount and excitement behind it compared to previous years seem lackluster.  Sony was all about the Move (which seems like a fancier Wii Remote) and the only game they showed off that I liked was Sorcery.  Microsoft was all about the Kinect, which still seems sorta lame with the exception of Child of Eden and Dance Central.  Nintendo was Nintendo.  I'm interested in the 3DS, but they couldn't really show it off.  The new Legend of Zelda, well, all I can say is that I haven't really enjoyed a Zelda game since Wind Waker.  I know I'm gonna get a lot of WTF comments, but Twilight Princess started off so slow that I couldn't get through the town.  I am really looking forward to Metroid: Other M though.  Maybe it's because I'm poor or just growing out of games that now I'm a dad or maybe it was a crappy E3 compared to previous years.  So how much will I game for the rest of the year?  Probably not as much.
 
As a note, I've attended 3 E3's.  2003-2005. 
 
On another note, I feel asleep at the 2003 E3 in the IGDA couch on the show floor in the middle of the day.  The midnight showing of The Matrix Reloaded was the night before and I didn't get to sleep until 3am and woke up at 6 or 7am to make it the convention center.
