Rocket League Ranks: Ranking system explained, MMR, rewards, and more

We all love a bit of frantic, fast-paced aerial car football, don't we? Rocket League stands in a field of its own as an esport, with its mixture of teamwork, coordination and driving skills making it hard to squeeze into any pre-existing genre.
Because it's so unique, Rocket League has a massive following and has become a top tier esport. But it isn't just the pro players who get to play competitively; Rocket League has a ranking system which allows you to progress from Unranked to Grand Champion across eight different competitive game modes. If you want to up your Rocket League game, or you're just a sucker for the grind, then ranked play is where you'll want to be.
For those who have maybe never played Rocket League before and are thinking about it now that it's going free-to-play on September 23, or have only ever played casually, you might have some burning questions about competitive play. Where do I start? How many ranks are there? How do I rank up? And, most importantly, how long does it take before I can say 'completed it, mate.'
