Common Sense Evaluation

You see, I’m a player
Of a great many games
So instead of just telling you,
Maybe try guessing my name

Now to make this more fair
I’ll give you some clues
For there are so many ways
That my name is used

My family is royal
Though as has oft been spoken
The headgear I once wore
Has since become broken

In my more playful moods
I might hide in a box
Or just run around, for
I’m nimble as a fox

But please don’t misjudge me;
I’m not some lame slacker
I can work hard with a hammer
To become a road cracker

If I see you in trouble
At the side of the road
I’ll be right there to help
If it eases the load

I’m brave in the darkness,
When it’s black, call my name
But I get rather scary
When I’m high on a plane

All right, one last clue
Then let’s call it a night:
I’ll give you a grin
As an October light

So now that we’ve ended
This fun guessing game
Now can you tell me
Just what is my name?
