There's not a lot we don't already know about BioShock 2 - takes place ten years later, you're a prototype Big Daddy taking orders from Tenenbaum. Apparently attempts have been made to make the combat more emphasis on setting up combat before you enter it. It worries me a little if only for the Little Sister protection mechanic - when a Sister in harvesting from a corpse, you have to protect her from attacking Splicers. Sound familiar?
Blur (in a n eight-page feature called 'Community Esprit' :lol) opens with the line "PGR is a game that hates players." :lol So Blur focuses on reward rather than challenge. Racing takes place in different cities and countries, with different styles of racing. It has 20-player online events, and local 4-player racing. All the characters in the game are connected to a social network (jokingly called, variously, 'Racebook', 'MyRace', and 'InnerTube'), which is essentially the game interface. It works as you'd expect, with race invitations, fan tracking, your car catalogue, all that stuff. But it doesn't look like your stats will upload to actual Facebook or anything like that. It's just a game mode. There is a separate one for multiplayer for sharing in-game photos etc, but there's no word on whether that will have a web presence.
What you can do is create a race mode that suits you, and put that on the in-game network that other people can join. Essentially that means you have a set of matchmaking playlists that are completely editable by the user. They talk about a group that removed all power-ups and had an honour rule that you had to shout 'Hasselhoff!' when you overtook someone.
