Here is an Xbox 1 tech demo of Heavenly Sword. No its not 360 like the video title suggests. a  quick trip to teamxbox.com confirms it was only in development for Xbox 1 and Xbox 360 was not even known to the world till E3 2005. This tech demo came out in 2004. This is very pretty for late Xbox 1.

Not saying this is all that representative of anything, but it is pretty interesting:

Resident Evil 4 Minimum Requirements:

btw i think everyone posting a pic or more about a game or maybe ten games also should have to post the same levels as videos so people can see how it really looks in motion with pop-ups and everything. because we all know pictures only show half the truth, right?

no it doesnt the gamecube A button is much larger in the first pick than the others(xbox)...

Interstingly you choose the laaunch title for Xbox rather than the comparable timeframe Halo 2.

Halo 2

OS: Windows Vista™
Processor: 2 Ghz Pentium   4 class processor (or x64)
RAM: 1 GB
Hard Drive: 7 GB
Video Card: DX9 graphics card: WDDM driver, PS 2.0/32BPP, At least nVidia 6000  or ATI x700 or above
Online Multi-player: Internet connection for Games for Windows – LIVE
Drive: DVD-ROM drive

So gamecube had a yellow y button, a red b button and a blue x button???????

Also the GC grey x button was on the right not the left.

The image you think is GC is actually Xbox 1.

again no actual gameplay and it looks like crap better looks raven blade and its not gameplay :D

That is because of Windows Vista:

If you want to run Windows Vista on your PC, here's what it takes:

• 1 gigahertz (GHz) 32-bit (x86) or 64-bit (x64) processor

• 1 gigabyte (GB) of system memory (512 megabytes (MB) for Home Basic)

• 40 GB hard drive with at least 15 GB of available space (20 GB for Home Basic)

• Support for DirectX 9 graphics with WDDM and 128 MB of graphics memory (32 MB for Home Basic)

• DVD-ROM drive

• Audio Output

Vista made games run like shit ... a game that would run at 1600x1200@60fps on a PC would suddenly struggle to run at 1280x1024@30fps on Vista

hm ok that would sound plausible but i don't understand why b is on the right and x on the left then and why it has the xbox colors.

maybe lazy developrs no clue^^
