If you think E3 stopped being fun because they got rid of booth babes then maybe you need to reevaluate your life, and join us in the 21st century. It's not that great right now, granted, but it's where I keep all my stuff.
E3 stopped being cool when the internet started ruining everything.
I remember the good old days of learning new stuff and reading about all the cool new games/systems. Now that stuff is leaked months before, companies have already pulled out, and E3 is just a zombie.
Sure I'd go if I could just to see it once but I'd honestly rather go to PAX.
