Suikoden 1 and 2 (and 3-5 + tactics, but they aren’t as rare), Valkyrie Profile 1 and 2, Steambot Chronicles, and Robot Alchemic Drive are the ones I know I have off the top of my head. I mainly keep the rare ones that I actually play or played in the past though; I’ve never been a big fan of keeping new games and letting them gather dust though I can understand the appeal.

Rule of Rose

Probably Pokémon sapphire from 2003 lol

NCAA Football ‘14 on the XBOX 360

Panzer Dragoon Saga. Only a few units were released in europe… Some people have offered some pornographic sums of money for it (best offer was 400€)

Final fantasy nes

Apparently, both versions of Yo-kai Watch Blasters!

On my old ps3 that my mom has it has mk9

An original version of Final Fantasy Tactics for PS1.

Otherwise a whole mess of Neo Geo arcade cardridges.

The Office, by Mumbo Jumbo, a Time Management game that makes me laugh. Also, like all the Mystery Masters (still collecting) on PC as well. Yoda Stories (Star Wars), all USA Virtual Boy games (Nintendo) and a few rare titles for PC by Sierra Entertainment (Phantasmagoria 1-2) and the original Half-Life (Sierra Studios).

My handheld console games would consist of Learn to Cook and Quitting Smoking (DS).

Despite the last two, I only choose the fun ones.

I have the first three Harry Potter games for PS2, Metal Gear Solid: Legacy Collection for PS3, and Zelda: WW & TP for Wii U, all sealed.

Z

Rarity Wise -

Dragon Ball Z Budokai Tenkaichi 2 PAL Sealed

Dragon Ball Budokai Tenkaichi 3 PAL Sealed

Spider-Man The Movie Game PC BIG BOX Sealed

Value wise - BT3 Sealed Hands Down (Now goes for $500+ Atleast and NTSC ones easily $1000+)

I’d have to say my “not for resale - demo only” SNES cartridge of Street Fighter II. However, it could be my in box (not sealed) copies with instructions of SM2 & SM3. The boxes are in near perfect condition.

Free epic game store games. They are so unwanted they must be rare
