We need to talk about your gaming closet.
Who, me?
Yes, you. Look, you have a problem.
No, I don’t.
Uh-hum:

Okay, maybe I do.
It’s time you start cleaning up this mess.
But where do I even start?
First, you’re going to take all those freaking kids puzzle boxes. Those boxes are all different sizes and shapes. We’re done putting up with that sh*t, okay? Be strong. For each puzzle, put the pieces in a plastic baggy. Cut a small picture of the image from the box for reference and put that in the baggy too.
Like this?

Yes, exactly. Now take all those baggies and store them in clear storage box with dividers and label them.

Perfectly stackable. Puzzles are done! Up next, little games: card games, dice games, on-the-go games, etc. Wouldn’t it be great if they weren’t lost, scattered, buried, or stacked into pillars to hold up larger boxes? Did you know they fit perfectly in 4×6 photo storage boxes? See?

That’s so convenient!
Oh yeah. Buy yourself a couple of storage cases that can hold twelve of these bad boys and you’ll be set.

Wow. Easy to search and ready to go! So, we’re done now, right? Surely there’s nothing else we can possibly do.
Hold on to your mittens, kitten, because you’re going to pick a few games to throw away.
*Gasp* I can’t throw out games! What if I might want to play them again someday?!
Seriously. Not only was Such & Such a sh*tty game to begin with, you haven’t even opened it since 2006. Ten years you’ve been holding on to this crap. TEN YEARS! It’s time to pull an Elsa and let it go, mmmkay?
*cries* *recycles* *tosses*
Thanks. I know that wasn’t easy for you. Now comes the easiest part. You’re going to shelf the board games vertically like books. If you’re feeling fancy, you can even rubber-band them up so they don’t accidentally spill open.

And we’re done.
Squee!
