This is a site suggestion, and my brother (LuigiWolf) wants me to say this, so I will-
Maybe we could have some kind of Submitted Games thing, with screenshots, and movies and all that. However, you don't actually put the games up for download, just as you don't for TMK. If you're confused, look at SMBHQ's Game Ideas section.
There, I said it. I hope my brother is happy...
Actually, I kinda want this too!
