** spoiler alert ?? **  ...  (i will try to do not so much though, speaking in a coded way)

all this below are just things i thought... in fact everything i say always is what i thougth,... you don't have to get it too serious if you don't want to

... i remember when i play an earlier version of the game and defeat XX and val's story turns unexpected..... it blows my mlnd

it remembered me when i watched "total recall" movie (the original with schwarzenegger), at some point he discovered his life was not as he thought...  same with "the 6th day" (also scharzenegger),  "the matrix" (keanu reeves), "memento" (guy pearce) and other movies  .... i think  there are many things that make what you are, like your body(es), personality, memories, feelings, stuff, circumstances, etc....  changing what you think you are is (at least for me) a **very** powerful element in role playing, especially in a dystopic rpg game,

in some games, alternative/parallel/past stories can be played, for example in  starcraft2 terran campaign, zeratul gives raynor his memories stored in a crystal that HE (raynor, the player) can replay in  "playable campaign" form.... same way the player could play val's alternative/parallel/past time lines

this way you could introduce a story that seems coherent to new players, that changes progressively through the game to go mind-blowing.... as the story progress it gets more disordered that the player has to sort himself , hooking him (like "memento" movie) .... this can be done more than once

something that could help is being dramatic in key moments in history inflection points ... use timings, effects, maybe being a little more exagerated or "hollywoddy" or theatrical, narrative, with expressions and emotions (maybe even a little overacted)... play with slow motions and closeups and lights, like some animes do.... to catch the player focus and make him say "whoa what a story!... i can't wait to know what's next".....

like i remember the first time i saw "the matrix", at some point (after neo takes the pill and wakes up the "reality") i didn't know WHAT movie i was watching and yelled WHAT THE FUUUUU .... i didn't understand NOTHING...  i felt like the movie tape was cutted off and joined with another movie, that triggered me the hungry to know what's next, until the end ....  i got shocked about a week, imagining wires from heads of  people on the street

what do you think about all of these?

forgive my bad english and fast witing, i am a spanish speaker (i am chilean)
