Im falling a bit behind so heres a bunch of new, incredibly easy hints for the next group of games:
#42:
Hint: In this non-God of War game, you can fight Kratos as a secret/optional boss.
#41:
Hint: The villanous group of this games has a ... "Flare" for the dramatic.
#40:
Hint: "No lollygaggin".
#39:
Hint: In this PS1 game at times you play segments as the main villain, who happens to be "the other half" of the main protagonist. Two parts of a whole, lets say.
