As much as im against the OP idea, I feel I need to jump in here to bring it back on topic
Because people are suddenly talking about their first maps experiences, mid game pollution etc.
I think with more and more of experience, every biter level is manageable, doesnt matter if you like it or not.
If you absolutly have to, you can always turn them off.
There are different reason, and all are valid
Im the first to admit that i first turned them off because they were too hard. I turned them on again and even completed a deathworld. Now i turn them off again, because there ARE a nuisence more than they are a threat and at the planned size of my base will only hurt in performance, nothing else
He HAS a point about the endgame biter scaling tho. IF you are into fighting biters as a motivation.
But i think its a philosophical problem, rather than a balance one.
Since its the only other recent game i play, i´ll compare Factorio to Rimworld:
In Rimworld, you kinda play tower defense. Or whatever the OP meant.
You tech up, you enhance your colony and pawns.
The harder the setting, the harder the events the game throws at you.
You can play it on peaceful, but thats rather dull, as it also doesn´t send you much "good" events either.
I haven´t ended a game since B18/1.0, but i guess even with peaceful setting, at the end you will still need to fight for your ship, to finally leave the planet.
Essencially, its almost the same, its about assigning jobs, build your colony with short routes, micromanage storage zones and crafting jobs etcs...
BUT the game tries to outright murder you, if you go above a certain number of pawns. The more your colony is worth, the more raiders with different behaviours get thrown at you and at more difficult settings you get nature events that work against you and non-humanoid factions that can really screw you and your colony up. To a point where you just lose the game.
Thats the base game, thats the design idea, or least what it evolved to (only playing since A16)
Imho, Factorio is different. Altho its also about automation/efficiency, it is NOT designed with a final showdown in mind.
Since you can tweak the settings to your likings, i wouldn´t mind lategame scaling biters.
IF the devs have time for that.
But a look at the forums recently (0.17 hype) you can see thats not where their focus is, or should be.
When you read between the lines, some FFF posts, even after 6 years, sound kinda surprised (if not frustrated) by the time it took them to get 0.17 released, with some of the planned features coming later than they planned/expected.
With that in mind, i dont understand anyone asking for a totally different gaming experience, when you can just mod it.
