Have you come across a great website full of free challenging games? Found a game that you really enjoy or have enjoyed playing? Put a link to it on here with an explanation of the type of game it is and why you recommend it!
To kick off the thread, I present to you:
This webpage has several free online adventure quests games...games where you have to do and find various things in order to complete the game. The Viridian Room is one example of this, but these are text-based games. I just finished The Mystery of Brankly Hall and after my brain has cooled down, I plan on trying some of the other games on this site.
If you were a fan of Choose Your Own Adventure books, you'll enjoy the games here!
