It's always great when Japanese developer Yoshio Ishii gets experimental, and his RPG, Parameters, is certainly that. It looks like an Excel Spreadsheet, and plays like a computer hacking scene from a 1980s action movie. It has no real graphics or story to speak of, and its focus is on the most often derided parts of role-playing games: grinding, farming, and stat-managing. But this simple game of mouse clicking and movement is strangely charming, and hard to stop playing.
It won't be for everyone. It takes more than a little abstract thinking to figure out what's going on. But much of the joy in playing Parameters comes from determining the mechanics for yourself. While not for the easily frustrated, Parameters is a hidden gem of a game that should be quite compelling to those in the mood for something a little strange or experimental.
