They could add Pong consoles to the Other Consoles tab so you can keep track of your Pong console's value. The First Generation of gaming needs a little love too.

The Switch is region free, and in a disturbingly increasing trend, the only retail versions of some games are from Japan.  I am Setsuna and Bayonetta 1 are only retail in Japan, but have full English versions!  But there is as yet no entries for these games.  Sadly, this will likely only become more common in the future, so I think it is an important thing to add!  Also, you don't even have to do prices, at least initially.  Just give us the option to add them to our collection.  I've noticed quite a few things that have no price but still let you add them.  Thanks!

Since shipping costs are determined by the seller, I feel that there are a lot of times where there are items are seemingly sold at a lower price but once you factor in shipping, the total cost is more in line with the market. I believe shipping is something most people consider when buying a game and therefore, it would be great if it could be included as a column in the historical list prices.

Is a price list coming

I have gotten to the point where I have amassed a good collection. I think it would be super cool for a weekend activity to have some sort of randomizer to choose a game from the collection to play. Also, to have a filter to filter out consoles or only include a select few. Not only to filter out consoles, but also features. Such as games that include multiplayer, or specific genre of game a person is in the mood to play. 

Is there any chance that you can add MetaZoo to the database?

Adding half grade (7.5,8.5,9.5, etc.) would be awesome in understanding the price differences between a half and full grade. Seeing a lot of 8.5 grades come back from CGC and the pricing compared to the full grade below and above is vastly different between cards.

The game Pokémon Rumble U had some NFC figurines like Skylanders and amiibos, which were actually created before amiibos, yet are not listed on this site. I would love it if they were on the site. Would make it way easier to buy/sell some to others!

It'd be nice to be able to see what's increasing/decreasing in value as a sort option in my personal collection.
