Microsofts E3 was kinda shit. I'll sum it up, it starts off with Halo 4, starting with a fantastic live-action scene, and then showing amazing gameplay footage, the game looks gorgeous, and the overall design of the levels, enemies, and even Chief's HUD reminds me a lot of Metroid Prime.Here's a video of it.
They then showed Splinter Cell Blacklist, which looks totally badass.
The rest was some stupid Kinect shit, some EA Sports crap, some fitness games... All this took up most of the conference.
They also showed off how Xbox is getting more TV shows (getting nickelodeon and some other great networks) and better sports event coverage, you pretty much don't even need cable if you have an Xbox, which is awesome.
They showed off gameplay of the new Tomb Raider which still looks great, as well as footage of the new South Park game, which looks hilariously fun.
To finish it off, they showed gameplay of Call of Duty Black Ops II, the demo was cut up, and whoever was playing was shit, so it wasn't really that enjoyable to watch, though I do still have some hopes for it since its being done by Treyarch, who add new stuff to the game, and try to be unique, unlike Infinity Ward.
Unfortunately they did not have a Summer of Xbox Live Arcade video showing off upcoming XBLA games like the previous E3s, which was a disappointment.
