So to make it easier to find horror games.

I've noticed that games which still have their cellophane on them are often as close to brand new as you can get, and will most often sell for more money than those without.

Scanner that lets user high quality uploaded Pics of fake and real Nintendo, sega, Atari video games to spot real and fake copies of Games, with the system telling the user if the cartridge game is a reproduction or not.

see above. :)

My idea is having multiple collection tabs within an overall collection. An example would be if you have two seperate shelves full of games you can make two seperate collections or just another tab so you can compare the two or more shelves together. Like the value and the amount of games on the shelf.

We have prices and charts on boxes, manuals, loose carts and CIB — BUT we have no prices on  the maps and posters and other inserts that ORIGINALLY came with many games which —for those games —are the diference between those three loose items and CIB. There is as much of a market for these map and poster inserts as there is for a loose game, box or manual so why no pricing for maps, posters and other original inserts? Lets face it —not that many games have been kept fully intact for the last 25 or 30 years. So in reality “CIB” games are mostly assembled after the fact from various parts purchased separately. These maps and posters are critical to that reassembling process and it is a handicap if we have no info on pricing for those essential components.

Would be awesome to be able to add pokemon mini games to my collection

It wold be great to add the option, without the price being charted, to allow users to have all of their collection based in one website. This way, I can put in that I have a Retron, a Tiger handheld game, or a Tele-Games Pong system without having to have a separate checklist. 

is there a reason for this? or is it possibly listed under something else
