A or C
I'll totally invent an alien biosphere if Kozmos wants me to.Don't listen to this crazy, this stuff doesn't matter at all for the level of development in question.
I'd vote A, if only because I've been working in that direction for about half a year and would like to see an attempt at it to guide me. Also because it sounds cool.
I'm curious, Luckymoose, if you could explain what you think it is, and what you think we think it is.
The only reason the ecology of the planet would matter in the slightest is if there is some product it produces that is difficult or impossible to get (or manufacture) anywhere else which may be of value to the more advanced exoplanetary polities vis-a-vis trade, e.g., Dune's spice. Or it presents an extremely notable hazard. (Protip: nobody would send a big important colony mission to such a planet. Probably.)
Nobody is going into stazNES XI, for example, really giving a damn about the distribution of yaks or tuna, because it's not important to a 21st century level understanding of geopolitics, international relations, or economics. So if the planet in question has a wonderfully unique weird chiral silicon-based biome that exists in uneasy tension with Earth-based carbon life but otherwise does nothing exceedingly economically useful, great: it isn't important at the level players will be operating at. You can spend time describing it, but it's frankly a waste of effort.
Economy in worldbuilding. Stuff That Matters First.
I think Symph was meaning when comparing planets in a Space Age setting, not Stone Age. If you are already fully space age developed, and only dropping in and raping a planet for its minerals, you won't really care how tall the trees are, or if there is a suitable pack-horse analogue. Taiga or jungle, you'll suck it dry and leave.
