Couple of very cool new videos to watch, above is an open world gameplay demo of Watch Dogs. Looks pretty cool, reminds me of a mix between GTA and Assassins Creed, I just hope you can choose to stop random scrubs from entering your single player experience, because that sounds like a way for all kinds of grief to happen.

Also, below is some gameplay from the DLC Expansion to XCOM: Enemy Unknown. Adding new units and new abilities to the existing campaign, this demo highlights some of them. It looks very scripted but still gives an impression of the new unit potential.
