I know this may be a little too late to say this... but I would advise against using a console game (this applies to anyone who's doing next years HSC).
I once did use a console game (FFVII...) for my english assessment, and I got good marks for it, however you need to search each and every feature of the game in order to get some sense out if it is to be related to journeys. When writing it in an essay (and I tell you that it does not look good in an essay) you have to be specific as one feature of a game can have multiple impications of a journey. You could even write 2-3 paragraphs on just one feature! But since you need to focus on other texts, using a console game is not a good idea...
