Heres a more thorough (although somewhat pessimistic) run-through of the acts at the Activision party, from my favorite game website, Kotaku. Also, I forgot to mention earlier one of the best parts of the evening: free beer, wine, and concession stand food! You could just walk up to any counter, order what you want, and they would ring you up for it. But then you could walk away without paying, with no fear of being tackled by a security guard! Later in the evening I think the Staples Center staff was anxious to charge Activision for as much food as they could, because they were literally walking up to people and handing them pretzels and boxed candy.
