I haven't done this in the past two years so I figured now's a good time to make one.
A few notes:
-My camera isn't the best... some of the pictures have inconsistant quality and I was too lazy to to back go and re-take them.
-I do have a lot of doubles, yes. And in nearly all cases, one of the two are sealed while the other is opened.
-Every game in my collection is complete with the original case/manual/disc(s) and any other extras.
-Not everything is pictured, a lot of my big box items are in my closet and I really don't feel like bringing them out.
-I've got a ton of pre-order goodies not pictured because it's too much of a hassle to keep out so they're in my closet.
-I keep a lot of my games in baggies, usually to protect them from surface scratches (especially the steelbook ones). So just because they look sealed, doesn't mean they are, I'll do my best to note these.
-I've got about 60 games and 50 guides which are on my tradelist and therefore not part of my collection.
-I've also got about 200 Transformers (mostly RiD and Armada) too but they're all boxed in my closet.
Anyway, here they are. Thumbnails are linked, pictures are 1600x1200 jpegs, in case that matters.
My room:
The set up: 32" Sharp LCD, Onkyo 7.1 receiver (using 5.1), Energy Classic satellites, and Polk PSW10 subwoofer, old 20GB 360, Wii, and 80GB 'MGS4 bundle' PS3, a DVD player which I leave to watch my TV because I'm too lazy to swap them with game discs on my PS3/360, 21" Samsung LCD, and my self built PC: 2.8GHz AMD X-2 (OC'd), Asus ATi HD 3850 (stock), 4GB DDR2800 memory, and 1.8TB over 4 HDs.
Fun facts: my room is very tiny... there's nothing interesting on the other half, only my bed.
GBA Games:
Notes: Harmony of Dissonance, Minish Cap, Ninja Five-O, and Super Mario Bros (NES Classic) are bagged, not sealed.
DS Games:
Notes: None of these are bagged, if they look sealed then they are. You'll notice 4 games at the bottom, which is where I keep my 'oversized' DS games- they're all sealed except for Luminous Arc 2.
DVDs:
Notes: I don't really watch movies that much but here's my DVDs and TV seasons. I only get them every now and then and only if they're cheap. Yes, I love The Simpsons. None are sealed.
PC, Xbox, and 360 Games:
Notes: The Gears 2 CE and Vesperia CE are both bagged. I had a lot more 360 games but got rid of a lot of my 360 games because the system is such an unreliable PoS. I have no idea why Metroid is there... but it's there.
Blu-Rays, and Wii and PSP Games:
Notes: Again, I don't watch too many movies and what I have, I only got because they were cheap. With the Wii games, you'll notice two black cases with names on the side, those are reminders for games I had but got rid of for some reason or another and need to buy again.
Gamecube Games:
Notes: The RE4 CE and Pure Evil 2 Pack are both bagged. Quite a few of my GC games are sealed but nothing noteworthy here.
Not pictured: Donkey Konga w/ Drums, Donkey Kong Jungle Beat w/ Drums, and Dance Dance Revolution Mario Mix w/ pad.
Fun Fact: The GC collection was my largest for a long time but has since fallen to 3rd (and likely forth soon with the DS catching up).
PS3 Games:
Notes: None of my CEs here are sealed, a few are bagged. Only a few of my regular games are sealed. The Fallout 3 CE is actually holding the GotY version of the game but with all the Fallout 3 CE bonuses/extras.
Not Pictured: GTAIV CE (the game's on the shelf but the extras are in the closet).
PS1 and NES Games:
Notes: The PS1 is my 2nd largest collection and is the one I put the most time and effort behind in building. Every game is complete with all extras (damn Atlus and WD games with all their little maps, charts, and dildos and whatnot). It also houses my only value version (GH, PC, or PH copy) of a game, a sealed GH copy of SotN. The only other game that's sealed is Silhouette Mirage, all the big boxed WD games are bagged. And there's also my NES games, nothing special here except one of the Castlevanias got half cut off from the picture but it's there.
Fun Fact: I'm only a few games and guides away from having a full PS1 RPG collection. I only have the Digimon World games/guides and a few other obscure game/guides left to get.
DC Games and my "Private Reserve" Games:
Notes: All the DC games excluded, all the games you see here are doubles and sealed and some are in special protective cases. Crisis Core and Xenosaga III are both special cover versions available from BestBuy.
Guides and large PC Games:
Notes: These are all of my strategy guides and every one is bagged (very few are actually sealed). I also have two of my big box PC games here because they don't fit anywhere else.
GB/GBC and PS2 Games:
Notes: The only sealed GB/GBC game I have is RE Gaiden, the others are bagged. About half of my PS2 collection is sealed, and the other is not. The only bagged PS2 game here is Ar Tonelico. King's Field is here because it doesn't fit with my other PS1 games.
PS2 Games:
Notes: Here's the rest of my PS2 collection. Only FFXII CE and the RE4 CE are bagged, the rest are a mixture of sealed/opened.
Not Pictured: Mana Khemia II CE, Guitar Hero w/ guitar, Devil Summoner 2 CE, and .hack GU Vol. 1 CE.
Fun Fact: The PS2 collection is my largest and really boomed due to me joining CAG nearly 6 years ago and as such, I bought a lot of crappy games solely because they were cheap. Damn you CAG! DAMN YOU!!!!
Fun Fact 2: Yes, what you see is correct, I actually have 3 copies of Xenosaga III: one sealed lenticular BB cover, one sealed regular version, and one complete lenticular BB cover.
Especially the complete boxed set Lunar 2 Eternal Blue. My copy is only complete with the case, discs, and inserts
