Breakaway 2010 freshman year, seeing 469 in person and fieldside Curie as a Team Media person, so naturally that got me hooked on finding the game breaking robot from each season.
Also that year was
2337 literally built part of the field on wheels and boy did it look incredible. Shame that it didn't pan out as they wanted it to. End game just wasn't weighted well enough.
Two years later, Rebound Rumble 2012, and 1717 literally swerved into my view and I fell in love with their robot. I've yet to see a drive train that can match that robot, and may D'penguineers rest in peace. (Still sad over that one.)
2056 in Ultimate Ascent 2013 was simply the epitome of building to seed first, and nailed that squarely on the head. I'll always love that robot in it's simplicity yet incredible grace.
