Again I'd like to point out that Dwarf Fortress ALREADY fulfils the definition being 3D - it has an X, Y, and Z axis. Hell, it really fulfils the definition of being a High Definition game. So I'm going to guess when people say '3D' they assume they want 3D models and for DF to look like Age of Mythology or Warcraft 3 or something.
Yeah, if Toady's smart, then the content is as divorced as possible from the rendering engine / event framework. But the fact is, we don't know, so we might as well assume a worst-case scenario and be pleasantly surprised.
And about that content... people are divided between it remaining 'flat' and using ASCII textures, and making it 3D like in today's RTS'. For the person that mentioned it, yes, DF would be the perfect candidate for procedural content generation, mainly because it's the only reasonable way to create that much content and still reasonably expect an update within a year. But if you're going to do it the old fashioned way... let's be realistic. Even if Toady throws DF to the wind and asks for users to create content for him (which has been pretty much proved will never be the case) - how many projects have you seen die because of the lack of shiny 3D content? Even if they get professional artists, it's still often months between releases of models, and until they're released, the project stalls (and often dies)
That's why I love that DF is ASCII. Because we don't have to wait for the art department because it's all abstracted away. E is for Elephant, and everyone knows what an E looks like. An E is an E and it's already on everyone's computer. It doesn't take anything special to use it, it doesn't require modification or texturing or animating or optimising or anything. Fonts by definition are easy to look at, easy to change colour, easily scaled up, and easily to replicate. And you don't have to be an artist to use it. Which means that we don't have to stall the addition of actual gameplay and stall releases because we're waiting on some Joe to finish the texture and Idling animation for Skeletal Groundhogs. You want Skeletal Groundhogs? G. There you go. What would of taken an art department weeks, I've just done in a second.
Once again, graphics are not gameplay.
But I really don't get a lot of people's arguements. DF is already 3D.
"Wouldn't it be cool if everything moved in 3D and we had smoke that trailed up into the sky and could push things off cliffs and they fell and went splat and we had terrain with slopes and dips and towering mountains and water that flowed around and lava too and wouldn't it be awesome if birds flew around in the sky?!?!?!"
You mean like it already does?
*sigh*
And CUBE is not voxelised. If you're going to make a pointless assertion, at least research your buzzwords.
