Here's another one of those games that you can buy while it's still being developed. In this case it'll cost you $10 for the alpha, with access to all updates and the final game for free. The developer reckons they need about a thousand sales to be able to complete the game to the standard they want. You can read the developers blurb below:
Tomes of Mephistopheles
Intro:
Before being imprisoned for eternity, Mephistopheles, the Lord of Darkness, put his sinister knowledge into several tomes which were scattered across the land. Many wicked souls were corrupted by the Devil and spent their lives searching for the wretched Tomes of Mephistopheles, to gain the knowledge of their unholy power. It has been foretold that the beholder of the Tomes will possess the greatest power known to mankind and will rule the world, but will corrupt it and leave it in ruins. The secret society known as the Deputies of Uriel dispatched its most skillful members to find the Tomes and destroy them at any cost. Will you fulfill your duty or succumb to the corruption of the Dark Lord ?
