What are YOUR games worth?

So I was looking up a few games on Amazon and noticed three that I own had skyrocketed in value.

(Kinda busy at the moment, so I can't provide any pictures)

Xenoblade Chronicles- $80

Fire Emblem: Path of Radiance- $70

Poke'mon Emerald- $70

My drumset for Rock Band 2: fucking $200 for some reason.

Dig up some classics and see what the nerds are willing to shell out for 'em.

I've been a collector since 2010 and this has always been a pretty reliable source.

Some of my rare/expensive games:
-Bonk's Adventure (NES)
-Demon's Crest
-Earthbound
-Gargoyle's Quest II
-Kid Dracula
-Mega Man 1
-Mega Man 7
-Mega Man Legends 2
-Phantasy Star I (took me 5 fucking months to find a good copy on Ebay)
-Shantae
-Xenoblade Chronicles

Pretty much all of them are good (except Bonk's Adventure, which was a terrible port, and MML2, which I haven't really gotten into yet).

Weird: Truth is Stranger than Fiction
really old mac game, can't find anything on it though.
might be worth a bit

Shantae's going for an assload now. You're one lucky skunk.

Recently I donated $90 to Wayforward's kickstarter for Shantae: Half-Genie Hero to get this dumb metal collector's coin and some other stuff. I've learned that collectibles can be an awesome, low-risk investment (Like this crummy Best of Super Mario Bros. Comics book I got at goodwill as a kid; worth $100 now).

The only game I can think of that I have that is worth something is the cartridge of Conker's Bad Fur Day. I traded a platinum copy of Jak 2 for it back in Primary school and the thing goes up to $189.99 on Ebay for the game alone.
