Hello, I wanted to know what are the minimum requirements of the personal computer to play.

The requirements are not finalized, but tentatively:

Intel Core Processor or equivalent is recommended (i.e. any CPU from the past 6 years or so; your mileage may vary with older CPUs)
512mb RAM
Windows 7, Windows Vista, or Windows XP
DirectX 9-compatible video card with Pixel Shader 2.0+ and Vertex Shader 1.1+ support
Desktop resolution of at least 1024x768 (1280x768 or higher is strongly recommended)

I've never heard it said. I would think most any computer would handle it as long as it could support Windows XP and higher.

The biggest thing is to have installed:
Micosoft .NET Framework 4 Extended
Microsoft Visual C++ 2010
Microsoft XNA Framework
Direct X 9 or greater

and all the hardware Mike said

This ensures compatibility with new things the programmer is working on.

mhhh ... cpu compared to gpu ... gpu is needed! weren´t 6 years ago a lot of pixel shader 1.x cards out? ... yet not so much but far far more than now

We have a lot of fancy graphics in the pipeline for the game which is why the graphics requirements are relatively modern compared to the processor.

This is a fair comment though Mike, you might want to consider adding this info to the download post. I'd do it myself but last time I edited the post you bit my head off.
