Is 343 leaving out important things from books?
I can think of some -Yoink- that you would never know just by playing the games and not have read the book or its summary.
These things include (i may be wrong on some)
-there are 2 didacts (no where in the game did it even hint at this)
-there are other spartan IIs (this could have been mentioned, but I don’t think so)
-why elites are attacking humans again (I don’t care if this was mentioned in grasslands or w/e, 343 should not expect you to read the book to understand the game, and no, “a lot can happen in 4 years” is not good enough)
