Super Mario Galaxy is back in all its space-exploring goodness — now in HD thanks to Super Mario 3D All-Stars! While many who’ve picked up 3D All-Stars have already played Galaxy, there are tons who are experiencing this iconic title for the very first time. Given the sheer number of games fans likely have in their backlog, it may be helpful to know how long it takes to completely finish Super Mario Galaxy so you can have a good idea of how much time you’ll be spending on Mario’s cosmos-hopping adventure.
How long does it take to beat Super Mario Galaxy?
It will take you an average of approximately 14.5 hours to finish the main story of Super Mario Galaxy. That means completing the entire campaign and collecting 60 Power Stars to fight Bowser, the final boss. However, you can also find yourself playing for just 9.5 hours if you rush it, or even as many as 25 hours if you take your time. Not all players have the same play style, though — and some may be after more than just finishing the storyline.
If you’re looking to collect the 60 optional Power Stars on top of finishing the main story, you’re probably going to be spending at least 25 hours on Super Mario Galaxy; 16.5 hours if you rush it and 42.5 hours if you take your time.
If you really want to 100% complete Super Mario Galaxy, you’re looking at about 42 hours to totally finish it. That means collecting 60 Power Stars, beating Bowser, collecting another 60 Power Stars, beating Bowser again to unlock “Super Luigi Galaxy,” playing the game again as Luigi and collecting another 120 Power Stars, beating Bowser again, and beating the Grand Finale Galaxy as both Mario and Luigi to get another two Power Stars. If you rush it, you can 100% the game in about 27 hours and you’ll beat it in 61.5 hours if you take your time.
