Alright, here's my collection. I didn't get around to sort out about 8 games (you can see some of them sitting on top of the big cabinet in the first pic). Due to time constants, I'm not doing highlights nor am I doing a separate post for my sealed games (we've gone though this enough times: some of us collect sealed games; get over it).
I'll distinguish my sealed games from my opened/complete games-- since some of them are in protective bags/boxes so they look sealed but are not.
Click the pics for bigger versions. Sorry for the shitty quality.
Semi-overall shot (can't fit my entire section in one pic).
Notes: Catherine CE (PS3, sealed), AC Brotherhood CE (PS3, sealed), God of War 3 CE and Killzone 3 CE are on the very top of the beige bookshelf but I guess I missed them in this pic.
Most of my PS3 collection.
Notes: On top shelf, everything from Bayontetta to Uncharted 2 are sealed. The rest are complete. Yakuza 4 and Uncharted 2 are PAL CEs.
My sealed DS collection and my sole 3DS game.
Notes: Yes, every game show here is sealed. Since I got an R4 and later AceKard, there's basically been no reason to open games.
Nearly every GC game.
Notes: I have a few sealed games, from Baten Kaitos Origins to Midway Arcade Treasures 3 near the middle. For the Wind Wakers, one is the regular one and the other one is the Wind Waker/OoT combo version. A few oversize games aren't pictured like Donkey Konga 1 & 2, Jungle Beat, and DDR Mario.
Most of my 360, Wii and Xbox games.
Notes: Sealed games are from Blue Dragon to Silent Hill on the top shelf for the 360, A Boy and His Blob to Zack & Wiki on the 2nd/3rd shelves for the Wii. On the bottom shelf, from Metal Slug 3 to Shenmue II, along with the Halo Triple pack, are all sealed (very hard to see these). Xenoblade is my opened import copy.
Some oversized CEs and guides.
Notes: On the very top, one of the Fallout New Vegas CE and Arkham City CE are sealed. In the two shelves, everything is sealed with the exception of one Hyperdimension Neptunia, one of the .hack GU Rebirth CEs, and Bully CE (very rare PS2 version). All the steelbooks there are empty. The Mana Khemia thing is the Jess figure from the Mana Khemia CE that NISA sold back in the day.
PS1 longboxes, a few more oversized CEs, and more guides.
Notes: Only the Dark Souls CE and Last Story (PAL import) are sealed. The steelbooks are empty. And no, your eyes aren't fooling you. There are some games hidden in the back. I rigged this shelf to fit as many games as possible since there was a lot of wasted space. The upper shelf is PS3/Wii/360 guides. The lower shelf is PSP, GBA, and DS and some midget sized guides.
All my Game Boy and DC games.
Notes: Only Jet Grind Radio is sealed, everything else there is opened/complete. And yes, that is a Barbie game you see.:lol: It's one of my rarest games according to DigitPress. The Game Boy games are probably the pride and joy of my collection and took an immense amount to time to collect. You'll be hard pressed to find these games in better shape IMO. These games are basically worthless but complete, most of these are easily worth $50-$150 each. The doubles for all the Final Fantasy games are due to one being the Square version and one being the SunSoft reprint. For Zelda and Kirby's Dream Land 2, I have one regular version and one Player's Choice version. For Mega Man I & II, there's a original version and Player's Choice version.
Most of my PSP games.
Notes: From Brave Story to Valkyrie Profile are sealed. I actually have a lot of copies of Crisis Core... on the top shelf: one sealed Best Buy exclusive foil version, one sealed regular version, one opened Best Buy foil version, and one opened PAL import CE.

There's also a PAL import Birth by Sleep CE.
Playstation 1 games (part1).
Notes: Such awesome memories here... my collection started here back in the day. That Greatest Hits SotN is sealed, the rest are complete. Tons of rarities here.
Playstation 1 games (part 2).
Notes: Only Silhouette Mirage is sealed, the rest are complete. These pictures were a bitch to take due to glare... and they still look like crap.
Game Boy Color and Game Boy Advance (part 1).
Notes: Nothing sealed here. Again, for the GB Color games, it was a PITA to find them complete/near mint shape. For Oracle of Ages/Seasons are one foil and one non-foil version. That tab on Silver means I need to replace the battery... I forgot all about that from last year.

Game Boy Advance (part 2) and rest of my DS games.
Notes: Nothing sealed here either.
Sealed Game Boy games.
Notes: Everything here is sealed... *sigh* back when CAG was fairly low-key and it was easy to get in on clearances/sales.

(
NES and SNES games.
Notes: I gave up on these two systems because it's simply too difficult to find games in good shape.
Large CEs, artbooks, and more guides.
Notes: Yup, I have a lot of guides. Nope, I don't collect random shit guides. I have a few import artbooks... most notable being the Xenogears Perfect Works. That red artbook (between the Breaking the Mold: BioShock and Xenoblade Archives artbooks is a Radiant Historia artbook).
And even more guides, including some CE guides.
Notes: A lot of those CE guides are actually sealed. That binder you see on the size is a work in progress, I put all the smaller artbooks (like from preorders) into a binder and will eventually put them in a nice, organized binder like in the last pic.
This is a very large cabinet.
Notes: It's very confusing inside this cabinet...
PS2 games.
Notes: The games on the doors are opened/complete and the ones on the back wall are sealed. There is one regular Shadow Hearts and a promo copy of Shadow Hearts. The Xenosaga III is the Best Buy lenticular cover. That silver looking box is Kingdom Hearts Final Mix Platinum Edition.
More PS2 games and some GC games, and a DS game.
Notes: Again, all the games on the back wall are sealed. Xenoblade is the PAL import bundle. There's one regular Persona 3 CE and a Persona 3 FES CE. That HeartGold is a WalMart exclusive version.
And more PS2, a few PS3, Wii and GC games.
Notes: Once again, the games on the back wall are sealed. That Xenosaga III is another Best Buy lenticular version.
Random mix of games.
Notes: (I'll go into the Saturn/Sega CD games in the next post.) All those PS3 CEs on the back wall are sealed and everything on the door besides Growlanser is sealed. The Pokemon Pearl and Diamond are Nintendo World store exclusives.
Saturn/Sega CD games.
Notes: Nothing sealed here, all complete. It's hard to find these games without cracked cases but not impossible. The two copies of Lunar are pretty neat.. one is a shitty, cheapo Sega print and the other is the nicer Working Designs print. I never knew about the two different versions until recently.
And that's it. Man, what an odyssey.
EDIT* Forgot about my PC games. Shame on me.
Notes: They're all opened/complete.
