Ran this for a group of friends who are mainly newbies or used to freeform RPGs. They picked it up in minutes, and we had a great time. If you're looking for a game with a fun mechanic and a lot of internal flexibility, this is it. If you're looking for a simulation or something with lots of realistic benchmarks, look elsewhere though. The actual results of play feel realistic enough, but I had some trouble getting one friend to accept the softer bits. I like using the ORE, especially if I'm homebrewing something, since it's so easy to create complexity without getting bogged down.
