Downtown Tokyo, Present Day

This game has an interesting opening; you are in a movie theatre, watching a giant monster movie. The game is in third person, with the main character's actions being narrated by the observer in the audience.

The actual action has a brief intro, followed by the actual puzzle. You move in 3d on a map with a ton of fake locations and some (labelled) real locations. This puzzle seemed really hard, but it turns out that there are 4 different solutions.

This is the only giant monster attack game I have played, and it was really fun in its sphere.

Although Downtown Tokyo, Present Day is most likely to be mentioned for its bipartite player character - you play the parts of both the hero in a monster B-movie and a cinema-goer in the audience - this game must surely be equally notable for demonstrating how a small set of commands can create a game that is diverse, malleable and above all fun.

All you need to do is fly your helicopter in compass directions, go up and down, and push the button that deploys its grabber - and in this fashion you explore the game's city, picking things up and dropping them experimentally, triggering various humorous responses from the parser, and doing all you can to save a nondescript love-interest from the clutches of a giant mutant chicken. There should be more IF games like this.
