It would be very helpful if there was some indication on the site about how in-demand a game is to be purchased on the site.   Either giving the total # of people who currently have the item on their wish list or a more generic statement saying the item is in high, medium, low demand.  Those of us who sell games can then use that to help push more inventory with a better idea if it will sell.

The historic game charts and collection charts always show values in US instead of my currency of choice.

Add value columns so I don't have to click on every game to see if it's gone up or down in value; literally just linking the data which is already displayed on individual game pages.

I love tracking the value of my individual Pokémon card collection, but I also have some sealed stuff that I’d like to track too using your website. Any chance you could add sealed product data?

Hello, I have a rather large number of steelbooks for games that were given away as bonus items for preordering and such. These steelbook don't come as part of a special edition and therefore it would be nice to be able to have them tracked alongside the rest of my collection as they are generally quite valuable (usually hovering around 40$). 

Here are some examples:

- New Super Mario Bros 2

- Ni No Kuni

- Arkham Asylum

- Skyward Sword

These steelbooks aren't specific to a given platform, so I would see them tracked using console = steelbook, like Amiiibo and Skylanders.

Given that I have dozens of those, I'd be happy to help build the database if this gets added.

I have one main game collection, and one collection of games that I intend to sell. I would like to be able to separate these collections on this site for a better overview of my games.
