It is self-explanatory. I'll give you a scale to go by. Worst on top, best on bottom.

Ratings:

Zero- The absolute worst you can get. You suck beyond belief. You have never beaten any game, even with infinite lives and unlimited health cheats.

A Lot Better From Zero- You still suck. You can only clear the first few levels of a game on the easiest settings. Maybe you can beat some extremely easy game with cheats.

Casual- You're not a good gamer, but you're not incredibly horrible. You can beat some games, many of which are considered kiddy and easy. You can beat a hard game with cheats.

Meh- You're a below average gamer. You can beat a lot of games, but not on hard difficulties. You can also barely beat hard games.

Average- You're average. You can beat easy games on hard, medium games on normal, and hard games on easy.

Good- You are good. You can beat some hard games on higher difficulties. You can also speed-run through ultra easy games.

Great- Your gaming skills are above average. You can clear most games on high difficulties, and you can beat a normal game 100%.

Incredible- You are very, very good at gaming. You can beat hard games on the highest difficulty, and can beat ultra-intense games on very low difficulty.

Epic Win- You are amazing. You can speed-run hard games and can get 100% on hard games on maximum difficulty.

Pwns0me- Holy shit you're incredible. You are able to beat some of the hardest games ever made on normal difficulties.

Truly 1337- You are elite at gaming. You can destroy anyone online. You can also defeat any game you want on any difficulty. You can beat ultra-intense games with game-modifying cheats to make it even more ultra-intensier.

RolStoppable- Oh. My. God. This is the best you could possibly ever hope for. You can do anything within the gaming world. You can set records for games that will leave everyone speechless. You are unbeatable in online. You can speed run the world's hardest game without so much as breaking a sweat. You are the best.

Leo-j- Lies about how good they are. Probably worse than zero. Loses on the Calculator in the Start menu. 2+2 comes up as 5.

I would rate myself as incredible.

Either Greary(whatever that is) or incredible. I tend to beat alot of games people don't like because of their difficulty.

I would put myself on Casual. I suck, specially on games like Brawl :(

Great, whatever...

I think I'm definitely between Pwns0me and RolStoppable. Proof is from my awesome gameplay videos on YouTube! ;)

Anyone ever beat Gradius III on the Arcade without dying once? That video is coming soon! xD

i am usually better then my friends at new games, but they get better then me with practice

edit: Average- You're average. You can beat easy games on hard, medium games on normal, and hard games on easy.

I would put myself at truly 1337.

So that would make you Truly 1337 SHMUP?

probably pwnsome or l33t.

I get too serious over games.

Somewhere between good and great. Probably closer to good. Except in Mario Tennis on the 64, I am amazing at that game.
