Future Boy! was a commercial game from 2004. A large game (it took me about 4 and a half hours, using hints 27 times), it has illustrations with gif-like animations for every room and character, as well as voice-acting for all dialogue.
The game is split into two parts, one with the parser, and one with little windows with graphics, usually one for the room itself, one for each character present, one for the compass rose, and one for effects like rain.
The game starts out fairly linearly, with a succession of challenges that set up the story. I found some of the early puzzles fairly difficult, which is unusual for commercial IF. I resorted to the hints as early as the second scenario.
After the first few scenes, the game opens up considerably. It ends up being reminiscent of Infocom's Hitchhiker's Guide to the Galaxy, with a cast of crazy characters and a variety of random locations that you can visit.
One of the highlights of the game is an unusually well developed (Spoiler - click to show)computer system. It's like a miniature game within a game, and gave me fond memories of the 90's.
My winning game was ~1500 turns long.
The plot is fairly intricate. Overall, I enjoyed this game. If it were an iPad app, I would price it at around $5-$10.
I came into possession of the game by contacting the creators using the email on the Future Boy! website.
