With the start of the new year, Dragonsphere will no longer be a free game on GOG.com due to new publisher agreements. If you haven't claimed a copy for yourself, make sure to do so by December 31, 22:59 PM GMT - afterwards the game will be regularly priced at $5.99.
“One of the last of the best graphic adventures of the mid-1990's, this fantasy game was full of surprises! It involved a kingdom threatened by a wizard so powerful, their only defense was to encase him in a mystic bubble. A small orb, the Dragonsphere, shows the rulers of this land how the shield is holding…and now, the orb has begun to crack!”

“An exciting new graphic adventure, packed with people and places to discover. It could be longer, allowing for more detailed interaction with the characters you meet. It's easy to lose yourself in this fresh, engaging game.”
