Do you think so? It's meant to be a program to encourage freewriting, and I find it useful as a prewriting exercise myself to get me into the right mode. It does save the text for use later if you actually manage anything meaningful, but I wouldn't really expect much XD.
I could see it either way - I wish I could dual-list it, I think I had it listed as a game initially. Ultimately I think it's a better as a tool (has better utility) than as a game (entertainment value).
After reviewing current usage, I decided to drop the utility tag. While I feel it's definitely in the category of tool - as it's a specialized text editor designed to enable writing, it certainly isn't designed for any kind of system management usage.
