nightrunner227: Reus may be extremely unlikely, but it does seem to fit the clues.
Will could refer to the free will mankind has in the game, and man could reference that man is the only thing you can't control. As for the "cover art," the eyes-looking thing in the corner could be the eyes of a god looking down, and the 4 could reference the 4 giants you control. And naturally, the R could be a reference to the title.
Yeah it fits the clues pretty well, I'm pretty sure it's not gonna be Reus though. Actually, I think that it's even more unlikely to be Reus because the clues are too obvious when you try to connect them to it.
ShiftySlug said the clues didn't make sense to him until he asked Jonny.. meaning the clues probably aren't supposed to be so obvious.
I think I may have found how "Man" and the new drawing connect to Stealth Bastard Deluxe though. Man could refer to "Hiding from The Man" which is in the game's description, and the new drawing can be perceived as a baby, which could relate to "bastard" child. The only clues that I can't match to Stealth Bastard are "4" and "Will".
EDIT: Actually maybe I'm wrong about the baby.. apparently the drawing is actually in the game..
