Its gonna play like half life 2 apparently they are focusing on a good single player experience and about bloody time with all this bullshit multilayer flying around now. There is interaction with characters and weapons need to be bought so I'm sure you can guess this will have some minor RPG element to it. Along with this, aliens colonial marines and Postal three next year already has me pretty pumped, though I was disappointed with this years list of games, except batman.. Metro 2033 is supposed to be out early next year - The next time we get an update for this game I reckon the bandwagon will really start rolling.
