Topic: You know you're a true gamer when...

when you go to a gaming convention and NEVER wear anything but a costume
when your room's walls are filled to the brim with gaming posters
when your computer overheats after playing "just one more" game of tetris
when you wait in front of a store for 2 months...just for a Final Fantasy spinoff
when you name your kid after a game character

Déjà vu I'm sure I've seen this topic before on NL.

You own My Aquarium. You know you do too.

Spirit Tracks? Yeah, I don't think so

and then the new wii Zelda?

That's classified

Back on topic...

You can race online against Twilightcrow in Mario-Kart Wii without cussing. Try it! It's tougher than it seems....

You Beat Battletoads without having to continue!
Wait thats impossible, how about just beating Battletoads!

Are you wanting more reasons and examples added ryanknight ?
If so.
You are still playing older consoles just as much as the newer ones.
You are an obsessive buyer and will buy a ton of old used games for past consoles and be more excited than a 5 year old on Christmas.
When a game is announced and it literally drives you nuts until its release and you finally have it in your hands.
When you go to the same two video game sites 100 times a day to just check on updates.
There is a ton of reasons that I could go on with !

Would I be a bad person if I concluded the sentence with, "...you can be able to finish Toy Story and Super Ghouls'n Ghosts without the invincibility and level skip codes enabled."?
...if you're not judgmental about Sony at all.
...if you give classics a chance.
...if you beat Star Parodier in one life (okay, that's just me).
...if you practice long enough to master as many games as possible.
...you collect every item in Zelda 3, and find every secret, without the aid of a guide - sans the Chris Houlihan room.
...you're proud of the games you own and have a blast with them.

Robin Williams named his daughter Zelda

Also, I always found the Chris Houlihan room in Zelda 3 by accident. I never realized it was a secret until I checked GameWinners for some glitch guides.

When you make forums threads like this

You mean I'm not a true gamer

I was just kidding.
Anyway, to be serious, you know you're a true gamer if you own at least one collectors edition.

What about I Wanna Be The Guy?

When you play a game and enjoy it, and don't feel the need to make up bizarre criteria to elevate yourself in your own esteem above other gamers.

When you have a sore thumb.
