Im very excited, after Prometheus and Colonial Marines, this could be the redemption. We need this!
I wouldn't worry about the gameplay that much, remember some people have already tried the 45minutes playable section and they all are praising the game. Colonial Marines gave nothing this substancial for the previews, it was all talk and lies, even the screenshots were fake.
In my eyes Sega will redeem itselt if Alien: Isolation delivers.
