There has been a lot of discussion comparing VRML/X3D to Second Life (SL) and MMORPG such as World of Warcraft (WOW). To some it appears that X3D is simply too difficult to use and the money is going to be made in SL or similar “user friendly environment” that are focused on social spaces and shared worlds. The argument further goes that building behaviors and hacking geometry in VRML/X3D are too difficult for mass market use.
