I knew that number looks familiar somehow

@Prometheus labs CEO
 
This number means that what is keeping track of the levels is 16-bit. The maximum value for 16-bit is 65,536 (remember though that 0 is counted). This is like those old 8-bit games that are supposed to never end but all kinda of messed up things happen when you reach level 256.
 

 
It’s much more likely you will see what happens when a value is stored at 8-bit then 16-bit (a lot of people pride themselves on reaching these “death screens” in the old arcade games).
 
Now they could have prevented this by patching it so the level no longer goes up when it reaches that amount. Or replacing it with 32-bit (then you would have to reach level 2,147,483,647 for it to crash).
 
The game crashes but it could have just as easily have gone back to level 0 instead (maybe it even tries to but there’s no stats assigned for level 0). I can’t imagine how annoyed someone would be if that somehow accidentally happened to them though…

@Communist Starlight  
That’s the level where if you reach it it crashes, I can’t blame them for not finding that glitch, I doubt quality checkers go that far

@Prometheus labs CEO  
Is that the “Lag cap”?

@Background Pony #DB66  
Level 65,535. I can’t blame them for not programming it to handle that

@Deserter
 
I don’t know if they ever patched it but technically if you get to a certain level, the game crashes every time you level up again. But it was a really high level that most players will never see (even if they finish all quests in the main game and the DLC, it would require a lot of grinding).
 
Also you would run out of perks before reaching that level.

@Communist Starlight
 
The drawback is that you have to plan in advance for it. Any perks that reduce radiation will mean less healing. So you have to make sure not to get those perks to take full advantage of it.

@Communist Starlight  
Really, in Fallout 4 everything’s worth the points, considering there isn’t a level nor SPECIAL cap.

@Background Pony #DB66  
That sounds like it’s worth the points

Also sometimes feral ghouls will ally with you.

@Background Pony #DB66  
What is it called again

@Communist Starlight
 
That’s great since I maxed out that perk in Fallout 4 that allows radiation to heal me.

That depends. How many are there?

I wonder how many Geiger counters she’s gonna set off

Hello Bone cancer

@Background Pony #B19D  
Wait, I thought those were all empty. Have I been looking at the picture wrong all this time?

Applejack: “‘Nuka-Cola Quantum’? Granny, what’s all this for?”  
Granny: “Oh, anybody who comes ‘cross needin’ it in the next two-hundred years ’r so.”

@BarryFromMars  
Why would a man want to wear a pair of these filthy woman’s pants?

MAH BOOZE

@Haymaker
 
Well thank ya kindly.

@BarryFromMars  
Eeyup.

That is supposed to be Nuka-Cola Quantum, Correct?

When Ronald (Or whatever the name of the character living near the girl who likes Nuka-Cola Quantum in Fallout 3, Is) said that I laughed.
