I don't think they're overrated, per se. Some of their stuff was pretty groundbreaking in it's time. Smart Robin still has one of the coolest and most "Hasbro would never come up with something like this!" transformations out there. I think the high regard a lot of people had for them back in the day was warranted. And on the other hand, I don't know too many people who love them the way they used to. They, and the 3P scene at large, have kind of moved on, to the point where even CHUG-style stuff is at least a Voyager with an expected minimum amount of articulation and minimal use of ball joints. Fansproject, though, still seems stuck in 2013.
