> Dell refuses to say what the engine can't do yet.
I'll go out on a limb here, and suggest it can't do real-time animation, texturing, lighting, shadows, collisions, etc. All the maps / screenshots shown seem to be static, procedurally generated and not artist-created.
Dell keeps throwing around this 'Unlimited Detail' marketing phrase which is very offputting. Until it's seen in action in an actual game it can be nothing but snake oil.
