This is a technical tour de force. Joey Jones has taken a random list of 10 IFDB games, including games in obscure formats, games that don't exist anymore, games just recently uploaded, French and German games, and an AIF game.
He implements each game, and you go through them. The AIF game is fortunately cut short, as are the French and German games, while the others are all happily tiny.
The game is surprisingly deeply implemented; for instance, the entire source code is included for one game.
This game really does recreate the IFDB experience, and provides an interesting commentary on IF in general. Also, the author has provided some small interaction between the small games. Strongly recommended.
