Things I love about this game:

* The emotions I felt while playing it and the valuable insight I gained from it about human experience and my own experiences. It was very intense. There are very few games that make me feel this much, especially over a relatively short playing period.

* Its unpredictability and flexibility.

* The integration of text and static images to create a fluid user interface.

* Whoever wrote this had a great sense of humor and knows when to say something directly (breaking the fourth-wall sometimes) and simply narrate. There is a distinct personality to the game.

* Frank, realistic depiction of sex and relationships.

* Variety in play experiences. My first time through I was abducted and murdered at age 3 or so, the third time I played I lived to age 80 and spent all my money on electronics equipment before death arrived.

I've played a lot of text adventures, focusing heavily on the ones without puzzles. This is one of the best, and I will play it several more times. A huge amount of work went into this game, as is made clear by the amount of small 1k files that make up the meat of the game.

I found this game at the original HOTU website.
I played it a couple of times, and it is a unique experience.
The lack of graphics just make it more fascinating. You are forced to picture it all in your head, just like when you're reading a book.
