I'd love to look for a series, say Castlevania, but only on a few

systems, like the PS1 and DS. Under "console" you could make it a select

all that apply, like ebay. 

Plug & Plays, such as the Jakks Pacific line of licensed "TV Games", and the Radica Plug & Plays. 

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 was looking around the website, and I noticed something: this websute diesnt have (much or any, im not 100% sure) educational games and consoles. I see this quite a lot that people overlook these kinds of consoles and games, which i understand, but I also think they should be listed here. There might be things like sega pico (i havent checked yet) but im talking things like leapfrog consoles (a.k.a leapster, leappad) especially since they have games like sonic on them, and u think that probably many collectors wish they could add these to their online collection so they can display them along with checking their prices. 

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!
