Tool/Modifier Idea
I was wondering if there is a Mirror tool that mirrors a 3D space in the blender file. Like I take a large cube /cuboid and Mirror the space inside it than hide it. now what ever objects I put in that space gets mirrored. this will make our life very easy when working with multiple objects like architectural game assets.

Basically what Jason said, most streamlined way to do it is with the GroupPro addon. Gives you really easy control over groups, nesting, flipping, viewing, adding to, removing from, and anything you would want to do with them from one pie menu no fuss. I've used it to create a partially symmetrical game environment. gumroad.com/l/GroupPro
If I'm understanding you, this is already possible. You can take all the elements in your scene and make them a part of a group. Then, create an instance of the group and scale that instance by -1. And there you go, mirrored scene, able to be placed anywhere.
