The stuff you mention here doesn't even have to be hand-placed, that can (and should) be done by PG in elite... the game desperately needs it, more variety in environmental assets and more things to discover. Space Engine is a great example of why Elite is so lacking; the former 'game' was made by a lone Russian dude and yet the PG galaxies & system there STILL have more interesting visual features than Elite's! They have comets, aurorae, tiny asteroid moonlets, planetary rings with proper lighting (eh-hem)...OK so this got me thinking. Why can't a PG game also incorporate handmade assets? Imagine a PG generated terrain with hills, forests, rivers, mountains, hills, meadows... then add in something that places a POI. For example, you're walking along and come across an old house that unbeknownst to you has a cave system under it. The POI is laid over the PG generated terrain.
In ED, there's no stars going supanova, no planets blow in half. It's pretty much exactly the same but in a slightly different order everywhere you go.
Additional - SC is dead? Haven't really been keeping up with it. It'd be nice to see a release though.
Those you suggest, i really want too; what about planetary nebulas, real accretion disks, embryo molten planets, planets which are so close to their star that one side is permanently molten..
