Hi guys, sorry you’ve had to wait so long for an ‘official’ response on this.
Long story short, we would love to release Shane’s mini games. As some of you correctly guessed, these were built two years ago so we would need to update the content significantly for Marketplace release. This doesn’t mean it won’t happen; we just don’t have a timeframe for it at the moment.
@amigo - That’s a cool idea regarding doing a prototyping contest among Epic’s devs. No reason why we couldn’t open up that sort of thing more widely to the community as well.
