I have too many games in my collection to keep track of mentally. I'd like to instantly see which games in a lot I already have so I can calculate weather or not it's worth buying a lot to get bulk games I need.

I'm trying to collect the entire PS3 catalog and having the option to only see games I do not have in my collection would greatly increase the efficiency of searching.

Please add prices for Japanese Mega Drive games!! There are a lot of exclusives that didn't even get an European release...

Also, thanks for already adding Famicom and Super Famicom!!

Adding The cartridges for the Texas Instruments TI-99/4A would be nifty .Mattels Hyperscan would be a shortlist  but might be nice as well. 

The Commodore Amiga CD32 is a CD based videogame console of the 90s. 

Please add support for it.

Thanks!

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. 

Please add support for foreign coins too

Having the ability to filter cards based on Ungraded price vs PSA 10 price would help those of us looking to buy raw cards on eBay that appear to be in mint condition (at least from the lousy potato phone pics) in hopes of getting those cards graded a PSA 10 for maximum profit or to hold for futures. There are several Pokémon cards that can be had Ungraded for under $15 and in a PSA 10 they go for $500+ depending on the card. Having the ability to see what cards could potentially 20x or 50x in value from their Ungraded price would be a rather unique feature.

I buying a bunch of Asia region games for the PS4 and Switch from Playasia and would love to track them. It'll be great to have those games included in my collection on here
