"Life In Rapture" or "What Do Splicers Do All Day?"
 

alot of them are either hold up somewhere or only encountered often because of constant respawning. If enemies didn't respawn you'd only run into a few dozen of them. Simple fact of the matter, most of Rapture is simply dead and only those at the top of the heirarchy would live much longer even if the player never appeared

everybody went into a crazy conflict where most of the commoners gained the ability to respawn shortly after death, and those that didn't were either killed or became tough enough to be considered a boss and/or become a big daddy.

And the little sisters are robots, ALL OF THEM.

1) they probably just dont know. Remember that was secretive information

2) do you really think roaming crack addicts are going to put the time and effort into destroying his magic immortality machine? which there are alot of? and dont really help him since he is nowhere near them? and its not full of adam?

Do you know what's going on in a crack addict's head? In a society of crack heads? Where the protectors of said crack are literally only interested in keeping the crack safe?

yes because its a crack addict, these aren't exactly complex individuals. They want more adam, if it doesn't get them more adam then they frankly dont care. All the factions with access to the stuff want those tubes working so no one will offer it for destroying them. There is simply nothing to be gained by destroying them.

Sure some were anyways from random violence, but remember how common they were and most of rapture was sealed off. Doubt you'd miss a few

I always just dismissed the Vita Chabers as part of the gameplay mechanic for most of the first game and never used them because it felt like cheating to me. Then they tried to shoehorn in an explaination about them being for Ryans private ressurrection uses, but made no effort to explain how the hell it worked or why the fuck he needs hundreds of the damn things everywhere.

And then somehow Delta can use them in the second game (I think, could Delta use Vita Chambers? Again I never used them so I can't quite remember) and made even less effort to explain that whole plot inconsistency.

Really the whole thing makes no sense and is best just ignored.

As for Splicers, I guess they just run around being insane and trying to track down ADAM, however they can. Admittedly there's probably varying levels of sanity, some people might be quite normal and well adjusted, certainly there are still a few normal people left in the city when Delta wakes up 10 years later, which begs the question why are they still stuck in that damn city of the dead?

And a more pressing question; if Splicers are all, by defination "spliced" and genetically modified, why do only a handful of them even have powers, when there are large amounts of plasmids out there with offensive capabilities that could aide them in aquiring yet more ADAM to feed their addiction?

Really the whole word of Rapture starts to make less sense the more you scrutinise it.

At that point you've already stopped caring and have continued your rampage with the chemical thrower.

Until the story explains how it happened very clearly and through direct narration of the event by Eleanor? I mean, I guess if you didn't bother to finish it you could have missed it, but it actually goes further to explain how Delta could use the chambers then the first did with Jack. You could easily put two-and-two together with Jack but the events around Delta's rebirth were a bit of a mystery up to that point.

I can understand missing a subtle point or clue, but when the lead female protagonist tells you directly as part of a story-controlled flash back I have to wonder.
