Game developers can use maps, weapons, and character models on their sites, not just screenshots, concept art, and video. This would be a good addition to the selection of the product.
I also see the possibility that people can record a game where it makes an explored 3D scene of a previously played match. This is already happening in Halo 3 and a few other names, but now we can share content on the Internet so that everyone can see.
People can also create 3D avatars (and no, I don't mean the little people who walk). Forums use animated GIFs and animated PNGs, which are often simple logos or symbols. Any video or animated image of a simple symbol or logo uses more data than an animated 3D object of the same thing (in most cases).
Last but not least, the creation of all 3D web pages. PHPBB could make it so that threads can be moved using the arrow keys or the mouse as you floated around the forum as a landscape. A forum can have rings of threads and for each thread with LARGE threads, more rings. Then, when you go to messages, you can click to load the previous page or the next page, and it will expand as a scroll.
I hope I have not confused anyone with the last two paragraphs (from time to time I confuse people). If you need explanations and sketches, write me an email: alexgoven@gmail.com.
I expect that there will be many wonderful things that we never thought before. This is not always about improving web functionality. Even feeling and navigation can go beyond our simple fantasies.
