If you are considering picking this game up do not wait as it is more of a modern masterpiece then a game. From the start you can tell there is a lot going on and nothing can prepare you for what will unfold in a dark but vibrant setting filled with a looming feel that things are always not as they seem.
Like I good book that you cannot put down I found myself forcing myself to stop playing instead of feeling that I had played enough so if you have concerns that this title will not live up to the original Deus Ex, you can lay them to rest. The story couldn't have stayed truer to the Deus Ex series and Square-Enix/Eidos Montreal have done what no publisher is willing to do these days and that is to make an amazing PC game.
So if Ubisoft, EA (Especially BioWare with ME3 on the horizon), Activision/Blizzard, Rockstar, 2kGames, Bethesda or other major publishers are paying attention look at what Square-Enix has done here and see how it is that you make a game for the PC.
When you release your next PC game, look at Deus Ex Human Revolution on the PC:
49.99 with 10% off on pre-order No install limits, internet connection required, phoning home or any other anti-consumer DRM On Steam and Retail stores Not a console port No Games for Windows Live or Origin etc. Runs at first launch with no issues
If it doesn't meet these points just don't bother releasing the PC version because Square-Enix, Valve and dozens of Indie developers will continue making games many others, including myself want and will gladly spend my money on those games instead.
