Pretty much just list all of the games you have but just never get around to playing/beating. Also you can suggest to someone which games they should play.

Currently my backlog consists of

Final Fantasy XII
Silent Hill 2
Demon's Souls
Deadly Premonition
Metro: Last Light.
Just Cause 2
Professor Layton and the Curious Village
Monster Hunter 3 Ultimate
Max Payne 1 & 2
A Fading Melody

Mass Effect Trilogy - sold by now, but I might play the PS3 version eventually cause I somehow just can't get into the game with German voices...
Persona 4 Arena - started it, found Story mode had way too freaking many words for a Fighting game's story mode. I'm waiting to get HD cables for the 360, so that maybe I can see what the damn controls are in the game finally...
Worms Collection - started playing when my husband was over last time, then didn't play anymore.
Mario Kart Double Dash - played once or twice when my husband was over, but not since.

Corpse party
Ore no Imouto ga Konnani Kawaii Wake ga Nai Portable
SDR2 (japanese version and waiting for translation)
One Piece Red Dawn (3DS)

I'm usually pretty good about beating the games I get... But there's a couple...
Luigi's Mansion: Dark Moon - The L and R buttons on my 3DS are completely dead. Ain't suckin' up ghosties with 'em!
Shin Megami Tensei - Devil Survivor 2 - Whenever I'd get stuck on a tough boss, I'd put the game aside for a couple weeks at the least. Then came and I pretty much ragequit. I've had the game for almost two years, and I still haven't actually beaten it!

The spongebob movie game has been on my backlog for 9 years now, i also have Drawn to life, Yugioh falsebound kingdom, Dave mirra BMX Challenge, Super mario 64.

Dragon Quest VIII. Damn Rhapthrone baby kept using that damn debuff so much I was like "Fuck this." Stopped playing.... need to cheat to beat his ass.

Harvest Moon A New Beginning.... Still single in the romance life. (Haven't played it in months to be honest)

Final Fantasy VIII (Emulated disk 2 have yet to complete it but plan on it)

I can't think of any more.

Because most of the games I got I already beaten with and without cheats.

---

OmG I totally forgot about my Harvest Moon Wonderful Life Special Edition... then again, I technically already played the game several times on the Gamecube, so I don't think this one really counts...? Then again, it has the problem of being... slow.

I'm pretty sure I've never even put that one into my system.

Same goes for about half of what I listed, so some of them might not even work. No way to tell...
