There will be a spectrum of worlds from Level 0 (Earthlike) to Level 7 (Otherworldly). The worlds we explored on the Hunt were deliberately the higher level and hence more extreme otherworldly landscapes. We deliberately explored these because we wanted footage that contrasted what exists on the current Live worlds.
There will be many many worlds with Earthlike palettes and biomes.
By atmosphere effects - I assume you’re referring to the day / night cycles and the sky colours?
Or are you referring to the particle effects that could be played throughout the different biomes?
There are and will be mountains on starter worlds.
But we require a spectrum of worlds and landscapes and biomes and palettes and effects, without this I fear that all the worlds will feel alike which will give players little reason to explore the universe.
This is exactly what we’re doing.
