This is something minor but helps make the world feel more immersive, and I know for a fact that this effect is easy to do in Unity, Interior Parallax Mapping. For those who do not know what this is, it is a shader technique that is used to make interior spaces look 3D from a cube map texture. A good example of this is the inaccessible apartment rooms in the new Spiderman games when you are crawling on the buildings and you look through the windows. These rooms look like real 3D spaces even though they aren't. So what I am suggesting is that for any interior with windows that are inaccessible to players, make use of interior parallax mapping to make the game immersive. And no, this effect isn't taxing on your device because it is just 1 cubemap texture that is being used to make the 3D looking space. This is what it looks like:

This would be really cool. I just hope they don't give it the gta 5 treatment of low res pictures ngl
