Apparently the game is very closely connected to the film, but games adventures [told by the Quark] will often be much longer [and filled of his exagerations and lies ] than in film.
The game does look in remarkable good shape for something not releasing for another year. I'm wondering if they could have shipped this fall no problem and only delayed the game to coincide with the film release after that was pushed into 2016. That's a bummer for Sony's first party lineup this year, but it's also possible they are only comfortable doing that because they have some surprises up their sleeve for the holidays.
