1. It works just fine for basic 3D functionality, but has limited support for tricks like fog FX etc. WebGL is actually quite capable when combined with simplified physics engines, and animated mesh packing formats.
2. In a business context it fails to check all the boxes, as people are not going to invest in a platform with near zero IP protection.
3. Steam + Unreal has all the advantages, and none of the problems/overhead of a Browser. i.e. peoples game pads, spacial audio, and shader cache buffers will work properly.
WebGL is just hitting the same VRML market that failed decades ago for the same reasons. =3
confused . There is no native desktop app for google maps. And it does full 3d. maybe you meant on mobile? But you brought up Steam so clearly not mobile
