Have you ever won an AAA game on SG?

Killing Floor, Dead Rising 2 - can count these ??

I won Borderlands 2... just day after my classmate bought retail copy, so then we could play together, hah ¦D

Dark Souls Prepare to Die Edition

The Witcher: Enhanced Edition Director's Cut

My very first win was BioShock Triple Pack.

The first Bioshock and Darkness 2.

GTA Vice City, Alan Wake, Dead Space 2, and Company of Heroes were AAA at their times, so yes, im yet to play them BUT I WILL... i promise.

Some of these are old AAA games.

Warhammer® 40,000: Dawn of War® - Game of the Year Edition, Medal of Honor™, Thief™ Gold, Hitman Collection, Borderlands, and Mirror's Edge™. If they count, also Poker Night at the Inventory and Game of Thrones - A Telltale Games Series.

Yes, I won Barbie™ Dreamhouse Party™ from Student123 :D

BioShock 2; and Supreme Commander 2, if we count it as a AAA title...

Does Tomb Raider count?

Darksiders 1&2

Grid Autosport, Back to the Future and The Dig are AAA right? and how bout King's Bounty: The Legend

I consider these "big" wins among all of my beloved treasures of wins:
Oceanhorn, Hyperdimension Neptunia Re;Birth1, Borderlands 2, Shadowrun: Dragonfall - Director's Cut, Valkyria Chronicles™, Lichdom: Battlemage, Batman™: Arkham Knight, The Witcher 2: Assassins of Kings Enhanced Edition, Bully: Scholarship Edition, Ori and the Blind Forest, Gauntlet™ Slayer Edition, Batman™: Arkham Origins, Life Is Strange™ (only the first episode though), Transistor + Soundtrack, The Bureau: XCOM Declassified, Grand Theft Auto: San Andreas, Thief, Deus Ex: Invisible War, The Witcher: Enhanced Edition Director's Cut, Deponia: The Complete Journey (which was my first ever win here)
Thanks to all the generous gifters!!

Assassin's Creed 2 Deluxe Edition
Crysis 2 - Maximum Edition
Fallout: New Vegas

View attached image.

I won the Fallout Collection (1, 2, and Tactics). I'd be hard pressed to find a better win, and although they're older and before the current AAA v. Indie market, I'd count them, because honestly, if you don't count the classics, then you're in pretty rough shape.

nope :(

Mad Max. Still can't believe it.

Also, Transistor.
Life is Strange (Ep. 1)
Far Cry Blood Dragon
Styx - Master of Shadows
The Wolf Among Us
F.E.A.R. 2 & 3
Bioshock Triple Pack
GTA San Andreas
Terraria
Dead Space 2
Serious Sam 3
Dragon Age: Origins

I'd probably consider most of my wins as "AAA"... mostly because for me "AAA" translates to "a game I can't afford or I think costs too much". :P

No...

Barbie Dreamhouse Party!

yep, Middle-earth: Shadow of Mordor.

Not yet, but I haven't been on SG for that long, so I'm sure eventually it will come.

Resident Evil 6
