here is a feature list of the extra version: http://www.conitec.net/english/gstudio/3dgs2.htm . But u cant use shader in the extra version (they would be too hard to program anyways). Try to start with a shooter it can stand out if it has great gameplay, graphics, ki, and so on. My advice for this is to start makeing a level put two players in and two guns and use the shooter template script for the movement and shooting and the enemy. Then look through those templates and see how it works and maybe start adding stuff to that script and to ur level and models to make it interesting and start building on that. It is important that u have a good foundation and then work your way up. A shooter is in my eyes the simplest and best way to start learning 3dgs and work through every tutorial that u can find they help a lot trust me. If u have any more questions just ask that is what the community is here for.
