First, your title is entirely in caps. That is not good. It makes it seem like you came up with this on a whim and want to get people all excited about it. In fact, your post pretty much says that outright anyway.
Next, what differentiates this from the PC itself? What use is there to put many games into what is essentially nothing more than a game launcher? If you just made individual games, you could release each one seperately and much sooner than if you tried to create a massive package of content. Also, if/when (most likely when) the project tanks, at least you might have gotten a simple game produced.
Finally, from your lack of details, it appears that you have no idea what you actually hope to achieve. Your post is poorly written and no one will follow someone who writes or communicates poorly. It is one thing to tell a real life friend about an idea; it is an entirely different matter to pitch a development project to strangers on the internet and actually earn their confidence.
