If this was always the intended design, just make this method the standard method, and the othe way the alternate. Wouldn't you agree? Thanks for the kit!
No, as South Park, Family Guy and Ghostbusters are really the only designs that mounting them in the "3D" method is really important. Other designs like Lord of the Rings, the AC/DC devil girls and the Iron Man figure also benefit from it. The vast majority of the designs look fine and just as good if you mount the grill directly behind the design. Others (mostly black designs) look really cool being behind the grills. That way you can't see the design at all until the game and light kit are turned on. As stated, the different mounting methods are described in the instruction manual as well as encouraging people to try the different mounting methods to see which they prefer.
Of the games I have had the light kits and designs in, I had my blue X-Men X mounted behind the grill. In my Black Spider-Man I have the design in front and the grill mounted directly behind it. I still haven't put a light kit in my South Park, but I'm sure the design will be in front and the grill in back on that one. With my Iron Man (which I also do not have a light kit installed in) I think I will go with an acrylic design double stack. That is, the Iron Man figure in the front, then the light frame, then a silver mirror Arc Reactor design, then the grill and speaker. I have a light kit in my Rolling Stones LE, but I don't use a design in it as the LE has the Rolling Stones logo painted on the speaker grills. In those cases, it's best to have the grills mounted behind the light frames so the lights will light up the painted designs on the grills, instead or lighting them from behind and washing out the painted designs.
So, there are different, perfectly acceptable, ways to mount the various designs. A person can mount them anyway they want, but I think some ways definitely look better than others, depending on the design. I also know there may be circumstances or a person's preferences that may limit the way they want to mount them.
