What i like about all four choices is that they are all adding content that sprawls across the whole game, meaning: from early, to mid, to end -game. Making the game even more "open-world-sandbox", really earning the predicate: simulation!
(Too many, especially text and novel type, games update by just stretching out the endgame ridiculously long, but adding nothing to the whole , becoming endless, on-rails, click-through -sausages. )
Will most likely vote for #3 but #1 is also tempting.
Could #4 maybe be a rolling update? Slowly adding one personality after another?
Caught myself asking this because i'm eagerly longing for the goth-girls ;)
Ps.: The next small polishing updates will be my personal big updates, because details matter!
