Thank you for sparing me the rant I was inhaling to deliver.
The system is so good. You wanna run a political intrigue campaign? Great! Not only are there dozens of skills to navigate the nuances of that style, but there are multiple supplemental guides if you want to get real nitty gritty. You wanna run a hyper-tactical combat heavy campaign? Great! The combat can be extremely rich, with an entire book dedicated to Martial Arts.
You can run any setting you can think of: sci-fi, fantasy, modern, historical, cinematic, realistic. The mechanics are there. But the base system is so simple and modular, you can run it off an index card. I almost think of it less as an RPG than an RPG engine. You really can adapt it to any kind of game concept.
