The DRM-free web site GoG.com isn't done with us yet this week. The classic PC game site has a couple of extra additions to their growing library to tell you about. One of them is Personal Nightmare, a classic horror-adventure game from developer Adventure Soft. It was released way back in 1989 making this title the oldest in GoG.com's library. You can download and play it now for $5.99.

GoG.com has also added Crystals of Arborea and Ishar III to its Ishar Compilation of RPG games. You can now get all four games in the series for just $5.99. If you already bought the collection when it just had two games, you can now get the two additional titles for free.
