pluggable graphics

I'm just starting to get into graphics programming and I might be getting ahead of myself but...

Would it be possible to create a game where you have your game module and then you have a graphics module that interprets the information sent from the game module, so you can essentially have the graphics module swappable for example different versions of openGl?

let's say I have two computers, one has a graphics card that supports opengl4 and the other has opengl3 or even lower.

I hope by making the graphics modules interchangable you can write graphics code that fully utilizes features of 4, and another for a different version. eventually when newer versions of openGl are release you can just create a newer module taking advantage of newer features so the game can age and not have to worry about getting to the point of being so old that nothing will run it except for a virtual machine.

I don't know if you can already do that or if it's just to hard to implement but I was hoping I could get some insight.

What the fuck does Gentoo have to do with anything? I use it as my main operating system and I could say making packages for it is as easy as it gets, because you don't even have to ship binaries.

If you want to make a game engine but you don't even know what dynamic linking is, I'm sure you're going to have a hard time.
