I feel that there should not even be any videos on the Tribute Site, ESPECIALLY speedrun videos.
No vidoes, because it would give away too many spoilers such that people who visit the site would know too much of the storyline, making them less interested in the game.
Also, especially not speedruns because it's The Sacred Grounds, a bonus which you can only access if you have taken the right path in the game. If a speedrun video were to be put up, they would, like I said before, get too many spoilers such that they would lose interest in restarting the game to get the different endings.
It's only obvious that you would start thinking that i'm contradicting myself as I supported the upload of screenshots to the site.
Well, screenshots don't give away as many spoilers as a video. This is mainly because it isn't animated, so gameplay method and movements are not shown in a screenshot. However, they are in a video.
And then you'll go on arguing that there are already speedrun videos on YouTube, so why not here?
Well, the reason we have a Tribute Site is because we want to promote the game, amirite (correct me if I'm wrong =X)? And since YouTube doesn't share the same purpose, I feel that whatever's on YouTube has completely nothing to do with this Tribute Site.
Furthermore, people who are new to Cave Story would not know enough of the game to be able to search for speedrun videos on Google, due to the fact that they would not even know what a speedrun is in Cave Story. However, they would at least know the name of the game, and with that knowledge, would search Google for "Cave Story". In doing so, it would lead the person to our Tribute Site. If the new player views the vids, then he would get too many spoilers and would lose interest in the game.
I feel that if videos are to be put up on the site, then the link that brings viewers of the site loaded with vids should first link the viewer to a warning page that notifies him/her of the spoilers the following page may contain.
Edit-
My Engeris be sucka.
