3D is difficult in GM, but it isn't stopping me from making a game on the scale of something like Halo 3. Yes, it's much harder to work with GM's 3D versus other dedicated, more capable engines, but it doesn't mean it's entirely unfeasible; half the fun I get out of development is how much I've had to work on things that are an easy given in other engines. Mark Overmars stated in the manual that you wouldn't be able to make the next Doom or Quake with even version 6.1 which first introduced 3D, but even back then, my game was on a much larger scale than either of those two franchises in their early years, and with all the advancements YoYo has made over the years, including compiling and shaders, the potential for decent 3D games has vastly grown. Even so, I wouldn't recommend GameMaker for any serious 3D development considering how much low-level stuff you'll have to design from scratch, but that doesn't mean it isn't capable of any of it. You definitely won't be designing stuff capable of being on the same level as other major engines on their worst days, but you can still get some decent stuff out of GM if you really commit.
And no, no pics. Not yet.
