"Photopia," is an intriguing piece that makes great use of color.
The production value of this game is second to none. Typically I am a fan of the elegant simplicity of the plain text interface. I have gone through this work in black and white and in color with the *.z5 file. But by far the best experience is through the blorb file. The use of color is one of the subtle additions to Interactive Fiction.
Through the years, IF has grown beyond mere text. Even in the '80's, Infocom experimented with sound and graphics. Contemporary IF has available high quality graphics, sounds, music, and even colored text.
Without a compelling story, all of the added effects won't make a mediocre game good. The added effects of "Photopia," take an intriguing game and bring it to the next level.
The skill level needed to enjoy this work is minimal. This would be a perfect introduction to IF, especially for those who are coming into the game from a more literary background.
All in all, this is a fine piece of IF that's a pleasure to play.
