The trailer seems to do a good job showing off what the games about. I liked how they used the timeshifting into game abilities. Its been a while in the making and from the impression i got the polish seems to shine.
Now if they phase the ability gaining well make them fun to play and interwine it together with a somewhat good story it has good potential. I hope Raven puts out a good single player game that will sell well. Since Heretic all the way to Soldier of Fortune i like to seesome old skool developers stick around. Since SoF3 they havnt released any original IP just quake 4 and wolfensteins? Im pretty sure they need this game to sell well from a financial position, Activision will leave nothing of them otherwise. :( I hope with them it does, and i think it could. :)
