First of all, my experience with Dungeonland was lovely. However, Triangle Agency is a mixed bag. It's hard to run, overflowing with mechanics and ideas but fails to hone in on them. It's anti-corporate messaging is derivative but executed in a new and interesting fashion with some exceptional art and layout design. Mechanical innovation is where it shines and I would highly reccomend to designers or groups willing to tough out the wonkiness. The Playwall is a highlight despite mixed quality of the things behind it. Run in short campaigns around 6-8 sessions. Get to meta stuff over missions.
