Actually you have a point, after reading the first page you would think that you need to download it all.
The main game is: 8.2 image file and 8.2 sounds (if you want) and the QSP file. This is all you need to play. Didn't state that. The other files are the dev build that are posted here to get feedback.
Kevin Smarts you have the google download with the main game and the mega download is the main game and developers.
Perhaps a separate mega with only the main game and stated as such on the main page.
