Re: The Window (Rules Set)
The Window is okay, but I don't find myself using it anymore. Generally, I feel like the things it sets out to do (rules light, descriptive characters, story-emphasized roleplay) are better accomplished and reinforced by other games, like FATE, Wushu, PDQ, and Cortex+, among others.
Some people find the Window's foreword to be kind of condescending and abrasive as well, but I see that as worth looking past if you like the system. As far as I know it comes from a different era of gaming, and that bluntness probably worked as a way to clearly establish what it was all about. I guess I can see how it might rub someone the wrong way, though.
