Yes, MojoWorld is still fun to use for no-trees planetscapes and I believe the final 3.1.1. Pro can now be found at the Internet Archive. The problem is the rendering speed, as it was never able to take advantage of modern methods. I think there's a discussion thread on this, on the Renderosity MojoWorld Forum. An install of Poser 6 (can only be 6) is needed to get Poser .PZ3 files into a MojoWorld planetscape. It's sometimes amusing to see various technical papers from 3D academics today, when you realise that what they're trying to re-create is basically... MojoWorld. Such a pity it was never developed to have fast rendering.

But I'd still look at the latest Vue, if it can be run on your OS (I assume the new PC has Windows 11 on it), and if you can bear a subscription. Even a year would enable you to see if it's for you, or if you need to go to Terragen, Gaea or to a real-time engine.

Finally, I'd note that Poser 13 uses the latest Blender Cycles engine (re-branded in Poser as Superfly), so may be an easier option to use than spending years learning Blender just to use Cycles rendering. I guess DAZ Studio many even be an option these days, as it has a lot of (costly) outdoor scenes, terrains and vegetation available. But I guess that with either you'll lack a certain something in terms of Vue's lush atmospheres and vast distances.
