Great idea and nice picker of starting planet. I enthusiastically crashed my rocket on Fulgora and Vulcanus, and found that I couldn't make water for the steam engine on Vulcanus, nor unlock the generator and electronics on Fulgora. I can't get wood for the small electrical poles on both planets.

I couldn't get research going on either planet.

It's possible to land naked on them in a normal game and build a rocket silo. But without the technologies (power poles, solars, accumulators, chemistry) a space castaway is stuck on them.

Which could be solved by other mods and leave this as a nice basis. Or tighten this mod up, because it's an interesting challenge to start on every inner planet. :)

I like the idea of allowing you to use other mods to fix the shortcomings. I'm already working on tweaks to the tech tree and/or recipes to make it possible to bootstrap on any planet from scratch, but I might make that a feature you can opt out of in case someone prefers other alterations or some other quickstart mod.

I would like to request that feature being opt-out, especially because then other mods can be made that build on this

All of the changes are already configurable! They're all in the mod settings and can be turned off entirely. The only thing you can't turn off is the planet selection screen.

Though it is possible to have zero planets selected. Maybe I'll add a case that skips the select and drops you on Nauvis if that happens.

Amazing! I'm still working on my first playthrough of Space Age, but when I'm done I'll be playing from this mod :). This does raise a question, does this mod support multiplayer with each player starting on a different planet, and if not, could it?

Yeah multiplayer support is the entire reason for this mod's existence! The other options at the time of me writing it only supported changing the starting planet for all players in a game, whereas mine lets each player select whichever planet they like.

Everyone can start on the same planet, all on different planets, or any combination really. It doesn't add new planets or split people into different forces. All the changes to the tech are simply whatever the minimum I can figure out to make it possible to actually get into space from each planet from scratch. Theoretically if you turned off all the changes and at least one person started on Nauvis everything would be possible without changes (it'd just be a bit boring waiting around for some players until the Nauvis player got some research done.)
