I think Mercari should be used to check prices against in the market as they are becoming a heavy hitter for resale.

I'd like to request the addition of the the Tapwave Zodiac to the 'Other Systems' category. Consoles include the Tapwave 1 (32MB) and Tapwave 2 (128MB), as well as first editions of each model. Games include Doom II, Duke Nukem Mobile, GTS Racing Challenge, Spy Hunter, Tiger Team: Apache vs Hind, Tony Hawk's Pro Skater 4, Z Pak: Adventure and Z Pak: Fun. This is an uncommon system that would benefit from having its historical price data saved on PriceCharting!

Apple II had a long run from the late 70's to the 90's and there were lots of games that came out on the computer. many are exclusive to it. So please add this list. Thank you

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

Add price tracking for Amstrad GX4000 game console and library.

I know that there are tons of clone consoles, but I feel that the higher quality FPGA consoles should at least be listed and tracked on this site considering that they're the newest and best alternatives to original hardware.

Please include the RetroUSB AVS Console, MVS, Analogue NT, Analogue NT Mini, and Analogue Super NT.

I would like to see something like a price check app that bloops up when looking at ebay listings. I don't know if I'm explaining that right, but as an example say you're looking at a Super Mario Bros. listing on ebay for $15, the plugin would bloop and be like "we have this item valued at $5 and rising" or whatever

Add the Fairchild Channel F system and its library of games.

Add the Action Max video game console and games to the site
