Page for a game within a game?

Would it be acceptable to create a game page for a game that is played within another game? For example, in System Shock 2 there is a personal gaming device called a GamePIG. This device had games of its own that you can play withing SS2, incluing an Ultima-like RPG called Overworld Zero. Would it be acceptable to create a game page for Overworld Zero? It's a game in and of itself, and is not some little gimic -- it's a full RPG and can actually be completed. Obviously, allowing this would open up some interesting problems, like what would the platform be, GamePIG? But I thought I'd at least ask. 
 
Interesting note: Overworld Zero was so popular among the SS2 fans that someone ported it from the source code into a standalone java game. =)

I remember playing with the gamepig for a while (mostly minesweeper), then getting rid of it because it was taking up too much space in my inventory D:
 
Anyway, I don't think any of the games warrant their own page but you could just write about them on the gamepig object page.

No, they've never been released on a real platform, so they don't get pages. They can be effectively documented on the System Shock 2 page, the Metagame page, and/or the GamePIG page.

That's what I figured, but it never hurts to ask. The GamePIG page is a good place for it. I can't seem to find enough information on the games made available for it to start a good write-up, though. I think I hit the end of the Internets. =/

" @risseless: You could always play the games, and write about them from that. And if there is little information available elsewhere on the internets, you'd be turning Giant Bomb into the definitive source for information on the GamePIG. How awesome would that be? "
