Which physical retro game in your collection are you most proud of owning? And why?

[GundamJehutyKai]

Oh yeah!!! I have a bunch of signed stuff I collected over the years...

Final Fantasy XIII signed by Kamikokuryo Isamu and Kitase Yoshimura
Final Fantasy 7 & The Last story Signed by Umatsu Nobuo
Parasite Eve signed by Shimamura Yoko
Xenosaga Episode 1 and Xenogears signed by Mitsuda Yasunori
Metal Gear Solid 3 & 4 signed by Kojima Hideo (the MGS3 one was funny cos he wasn't as well known then so I could just go into the store on the day, pick up the game, queue up and be out in a couple of hrs. Had to ask the security guard what the small queue was for. But MGS4 was a Big deal!)
One of my arcade sticks was signed by Harada and Ono...

I have a few signed posters lying about too but I forget where...

I'm fairly proud of my JP Saturn imports.

Most of stuff I'm proud of is hardware rather than games. Like my 1988 VA0 MegaDrive. Or my 1994 SCPH-1000 PlayStation.
I do still have my original Silent Hill for PlayStation that I bought new from a Walmart in 1999. I overheard an older couple standing in front of it discussing how much they enjoyed it so that's what I went home with that night.
I think what it really is; is my original Big Box BLOOD for PC though. I bought that new from an Electronics Boutique that got turned into a GameSlop years later.

Sorry it's not a picture of my actual box. It's in my parents attic. Maybe I'll update this and replace the image.

The copy of Super Metroid me and my cousin played through together as kids. It was originally his. I borrowed it one day and never returned it. He ended up going down a bad path in life and is unfortunately no longer here but it's still my favourite game to this day and playing through it the first time with my cousin is one of my most cherished gaming memories.

These. Posted before in another thread.

Friends said I was crazy for spending as much I did for each cart. Now with the AES+ coming, I don't seem so insane now do I fuckers?
Ports of Neo games don't "feel" the same. People will see depending how good the AES+ compared to the original system.

an NTSC-J copy of the first Shin Megami Tensei on the SNES that I got for a price that is basically free. I happened to get across it when going through a vintage surplus store here and it was also the time that I was very hyperfixiated with MegaTen
