Guys, I don't think it matters who came up with something first. Xerox came up with the mouse. Apple made the mouse into a game-changer. Microsoft made the Kinect. A bunch of hackers who were almost sued by Microsoft made the Kinect into a game changer (ironic isn't it?).

118's implementation of coaxial swerve was a game changer because of their promotion of it and its continued use. It obviously wasn't a game changer for 217 if they didn't use it after a couple of iterations.

148's implementation of sheet metal gears was publicized as being a game changer for their new drive train as well as part of the core mechanism for their 2011 bot. Who was the team in 2006 that did plate metal gears? Do they still do them and how did it revolutionize a system on their bot?

The WCD guys have found obvious success in the WCD since they don't use anything but WCD. They made WCD into a game changer, regardless of 'who did it first'.

Who did do that first? Do they still do it? Does the fact that they did it first matter? This isn't the commercial market where the first to do something can patent it and demand royalties from all of the future users, so I don't think it matters a single bit.
