In my opinion, out of the 3 hardware companies, Sony won E3. The Last of Us was by far the most impressive game out of the big 3. I got kind of disappointed that they had a lot more titles to show, like the new Sly Cooper, Ratchet and Clank, The Last Guardian, and they didnt. Still, it was the best. Oh, and the new content they announced for PS+ (which is available RIGHT NOW) was AMAZING. Theres so much value for that subscription, its worth every single cent. Theyre offering 12 full games this month, and some of these are huge AAA titles such as Infamous 2, LBP 2, Warhammer Space Marine and Just Cause 2. These games alone are worth much, MUCH more than the U$ 50 price tag for 1 year subscription.
But the best conference certainly came from Ubisoft. It was the only company to come up with a few surprises that didnt get leaked, like Splinter Cell Blacklight, and to finally bring some new IPs (Watch Dogs and Zombie U).
