Rune Full Version
Rune is a very old game, and it might be difficult to find a CD version of the game anymore. You could try online auction sites like eBay, Amazon and places like that.
The linux version of the game can still be bought from Tux Games.
There is also a Steam version of Rune called Rune Classic. You can get it from Steam Store.
If all else fails you can always play the demo version. 🙂
