This system is great! I run a campaign for some high schoolers and Maze Rats lets them pick things up quickly without having to squabble over the details. If they've played any rpg, tabletop or otherwise, they can jump right into the game.
The way the system is built lets their creativity come through, since there aren't many mechanics in the way of interesting solutions. The magic system might be my favorite part. The players and I will barter on the effects of a spell, and it really engages them.
The ease of use also makes it easy to port adventures from other systems. I've been running one-offs in Yoon-Suin (with a different group) and the two systems mesh well together.
Just get to the table, roll characters, and have an adventure. Highly recommended.
