🌟 Super Mario Galaxy is a beloved 3D platformer, and “100% completion” can mean different things depending on how deep you want to go. Let’s break it down:
⭐ What Counts as 100% in Super Mario Galaxy?
-
Collect all 120 Power Stars with Mario.
-
Unlock Luigi as a playable character, then collect another 120 stars with him.
-
After that, you unlock the final Grand Star and the “true ending.”
So, 100% completion = 242 Stars total.
🕒 Average Playtime
-
Main Story (just beating Bowser): ~15–20 hours
-
All 120 Stars with Mario: ~35–40 hours
-
100% Completion (Mario + Luigi, 242 Stars): ~60–70 hours on average
If you’re a speedrunner or very skilled, you could do it faster, but for most casual players:
-
Expect 50–70 hours for true 100%.
-
If you just want to see the credits once, you’ll need ~15–20 hours.
🎮 Tips for 100% Completion
-
Some stars, like the Purple Comet Stars, are more challenging and may take several tries.
-
The game rewards exploration—don’t rush; enjoy each galaxy.
-
If you want an extra challenge, try speedrunning categories (like “120 Star runs”), which competitive players do in under 7 hours!
✅ Answer in short: To 100% Super Mario Galaxy (all 242 stars), it usually takes 60–70 hours.
