I played the demo for about an hour and it seemed fun to me. I don't understand how by far the biggest complaints on OCN are it says "Press Start" and "Adjust TV Settings" like that is why I want to play Crysis 2. If only it said "Press Any Key" I would know the developers cared, not the thousands of hours put into the actual coding of a multi-platform engine and game.
I realize it just shows a lack of DEMO quality control, but these are issues that could be corrected in a few seconds of coding and likely already have been addressed. The DX11 issue, or lack there of, is disappointing, but again its almost all speculation at this point and doesn't dissuade me in the least in my decission to buy this game.
My feeling on this is Crytek really wants to push the sales on consoles, and are affraid if they release a Demo on PC that completely schitz on their console version, people are going to say, "OMGZZ!!! Why pay $59.99 on this dumbed down PC port!!!! Not worth it, I will keep playing COD:BO!!! Screw Crytek!" Thus ruining any kind of reputation they may build as a new top game studio, which would enable them to continue building on and improving Cryengine 3. Just my 2 cents.
