This is something I've been thinking about for a while. Basically, when looking through the files of some of the JumpStart games (typically by using a file extractor), it's possible to come across images or other content that doesn't appear in the game itself. It could be prototype content - early concept art for a certain location or character that changed by the time the game was released, or it could be something never even seen in the game at all, such as a location that was completely scrapped during development.
Previously I'd uploaded some unused content from JumpStart games to a site called The Cutting Room Floor, which is a wiki-type site that's entirely devoted to pre-release and unused content from all kinds of games. But now I think that this sort of content could go on this site too. I've noticed that some other wiki sites devoted to game series, such as the Mario wiki or Sonic wiki, have a fair amount of pre-release/unused content. I think we could do that here too, and I think the best way to go about it would be to have subpages for it. That way, when you go to a certain game's page, such as JumpStart 2nd Grade, you can choose to view unused content from that game by going to the subpage for it.
In some cases, there ends up being a ton of unused content for a game, and in other cases, there may be only one or two images. For the games with lots of content, it makes the most sense to have subpages. It doesn't make quite as much sense to have a whole subpage if a game only has one or two unused things, but even in that case, I think it's kind of preferable if the unused content has it's own "space" that isn't on the main article page for a game. So, even if a few of these subpages end up being kind of stubby, I think there would be an acceptable reason for it, in this case.
Anyways, I would be very interested to know other people's opinions on the matter. If anyone has suggestions for how to better incorporate this content, or if anyone thinks that we shouldn't incorporate this content into the wiki, I'd appreciate hearing your thoughts.
