Well, there’s a huge amount of misinformation in 's post, so let’s try and clear some things up for new members who might see this!
How exactly are they not offering a ‘complete item’, as you claim? They’re not only offering a compiled build of the engine, along with the launcher, but the complete source code. That’s certainly a ‘complete’ package right there. Similarly, Epic hae released animation sets, textures/materials/shaders, meshes/models and a huge amount of additional sample content. All of which you’ll find in the marketplace - for free!
I’m not completely sure what you mean by ‘marketing hype,’ exactly, because it’s rather clearly stated that it’s in on-going development still. The frequency of updates, hotfixes and so forth alone should have clearly demonstrated that to you. However, I’d argue that the product isn’t near as ‘buggy’ as you make out. I think that’s rather clearly proven by the amount of titles currently in development / already released using the engine.
This point here really makes you sound like a troll and nothing more. It’s hard to take you seriously from this point. Why? Because the usage of Maya or 3ds is completely nonessential. You could use any software / modeling package that you like. Blender will work, for example. It isn’t just FBX that can be imported, either - the engine supports other formats.
There’s countless ways to contact Epic directly. They’re extremely transparent on this, which really makes it seem like you haven’t tried. You do know that Facebook and Twitter exist, right?
I’ve already touched on the ‘marketing ploy’ nonsense and the like. Though, I’m utterly stunned by the statement of downloadable content. That’s even more silly. Epic aren’t asking you to pay any additional money for content they release and they’ve already put out a huge amount of sample projects to demonstrate the versatility of the engine. All of which, by the way, can be used commercially.
Is there a marketplace? Yes. It isn’t limited to Epic-created content, though. This was something that was asked for by the community as a whole. It’s a way for developers (or vendors) to sell content to developers, allowing them to prototype and iterate faster. If you don’t want to buy their content, you don’t have to do so. You’ll still have access to everything that Epic releases for free.
In the end, some people will never be happy!
