I love the level of almost religious interpretation of this steaming pile of fecal vomit, which goes so far beyond reading between the lines to just straight up inventing them. These deepities you've attributed to Mothership Zeta are simply not in the game. I've listened to all the tapes, checked every area, gotten the unique companion dialogue wherever possible, played it more times than I care to admit b/c I feel like a cheater if I just give myself the loot I can get there...I'm also an obsessively philosophical person. It was hollow, slapdash, and so poorly presented that it barely constitutes an actual story. You walk, you kill, you destroy, and then you get to go 'home'. If you punish yourself enough to get all the dialogue, all you'll find are boring characters giving the petty, irrelevant details of their lives with no particular significance, motif, or over arcing theme.
