Add a blurb for a "Why its this price" or "Cause History" to explain why some games are what they are
Here is a common occurance on this site. I come on and look up a game and notice the price is much higher than others like it. So, I go to Google and search "Why XYZ so expensive?" to read a blurb. Oh, this one had a limited run. Oh this one wasn't popular and came out late in the consoles lifetime. THIS ONE has manufacturing issues ah that makes sense.
So, instead of having me go to another site to find this information, just allow for a little blurb wiki style that people can enter text into, or edit, and people can vote or lilke or whatever to confirm it is accurate information.
Enriches the dataset you have, it is relevant information, prevents outlinking like I do by having to go somewhere else for the information. Seems like a no brainer to me, given the manpower to implement it.
