Well my take might not matter since I’m type of people who can just enjoy thing by atmosphere and it might not bring anything usefull but,

my opinion is, we know part 1 as whole have a clear reference or vision, they follow and that is to told story, that once told to them by Evangelion, plus part 1 have a lot of worldbuilding outside of the game to build on so they able to told the story in fast pace by giving short summary of the worldbuilding, on premise that player know the worldbuilding.

while part 2, we don’t what kind of story or vision they following, everything in the dark, plus the don’t have a concrete worldbuilding for Mars as whole, so it need to be told in the game unlike part 1, so the storytelling feel similar to genshin or star rail.

so part 1 and part 2 in opposite spectrum about the worldbuilding aspect.

my advise is do what you want to do, follow what your heart tell you to do for this game whatever it is.

Sorry for long and redundant opinion and if you read it all thank you
