Demo available, full version either MIA or never released

[Einar Saukas]

Here's a list of titles with an available demo, where a full version was never released:

Here's a list of titles with an available demo, where the full version supposedly exists but we don't have it (i.e MIA):

Perhaps some of these titles are not classified properly. For instance 1st of April Joke currently says "MIA (demo available)". However the game itself seems to contain the message "DEMO VERSION=LAST VERSION" thus suggesting a full version shouldn't exist. Can anyone confirm this information?

Are there any other cases classified incorrectly?
