I'm not buying those comments from "people that have connections to the game" Especially about the graphics. It wasn't just coding, lighting and texture quality that are different between the e3 demo and real thing. You levels themselves are entirely different layouts with different art assets etc The e3 demo is defs a "This is how we want the game to be" scripted/orchastrated or even pre-rendered sequence. And then they tried to make the game that way and failed. miserably.
I also don't buy the "SEGA and the two developers couldnt agree on the type of game they were making" you're telling they didnt have things planned out?
Its all BS - you can tell that the game only started development after the e3 2012 "gameplay" "demo" was shown and its a rush job and turned out as such.
