I've owned RAGE for 3 days with 13 days played. I just finished the campaign and I picked up and finished as many side jobs as I could. The confusing part: the game is 21GB in size!
I've owned Skyrm since it's release with 85 hours played with only 1 character with the MQ finished and many other side quests and dungeons yet to complete and explore. The confusing part: the game is 5GB in size!
I'm glad I picked up this game for $20 (on sale) or I would've been kind of upset. Some might say that I rushed through RAGE, which I did in a way, but trust me when I say I finished as many side things as I could before continuing any main storyline jobs.
Not sure if RAGE was console port like Skyrim was, but this is still confusing to me.
