Collections of specific game series regardless of console
I have cut back on collecting in recent years, except for certain series that I really enjoy, such as Zelda, Tales, Silent Hill, etc. It would be nice to be able to, for example, see all of the Castlevania games in one list regardless of which console they are on. That way if a game I want came out on more than one system, then I could see which ones it's on and how each has held their value. Also, being able to see which one is the original version in cases of games being ported after release would be helpful.

Return on investment for items in a collection
A function or graph that shows an ROI or return on investment from an input that a user enters as the value they purchased the game for and another to show current market price. Then gives ratios and graphed trends of specific titles over time.

Individual item price drop or rise
I would like to see the price drops and increases of individual items while still looking at the collection as a whole.

You can do that on the site now:
https://www.pricecharting.com/search-products?type=videogames&publisher=nintendo
There is a link on the home page to do the search (right below the console list). And you can get to the list by clicking on the publisher name on any game page too.

Update on UK Marketplace
Hi, is there an update for having a UK marketplace? We have a burgeoning games trade here but we’re all using FB Marketplace which is a bit hit and miss. Would love to hear any news on this topic!

"Platform Breakdown" Chart Generator
Another website I've used in the past is VGCollect and it has a nice feature to display your collection by platform. I think this would be interesting to see for both just raw number of games by platform but also value by platform using Price Charting data. Even if we couldn't get a chart, I think it'd be nice to be able to see the value of our collections by platform.

Add Arrows to show the value of a game going up, down, or the same (Up and Down arrows)
I like to be able to see at a glance if my items increase in value.
If they do, add a green up arrow,
if they stay the same, a yellow line,
and
if the go down, a red down arrow.

Add variations of the gameboy advance like target and toys r us edition
Add the red target and purple target gba. Add the toys r us edition as well

add "complete without box" or "loose with basic accessories" category for consoles
Just a thought, because people argue this with me every day. It would be really great if there was a way to distinguish between a console only and a console with cables/controller.. or at least spell it out, so that people don't argue that a console only is loose -- most of the time, those basic accessories can cost more than the console to acquire.
