Forza Motorsport 6 Xbox One Review: The One to Beat

The new Leagues are another multiplayer feature that I'm really impressed with. Basically, players of similar temperament are put together in a constantly rotating series of races. When I tried it, because I was new, I was put in at grass roots level, which doesn't have any collision detection. Assuming you're able to win races and rank up, you're promoted to higher-challenge leagues that have more stringent rules and, obviously, much better drivers. It's a novel idea, and one that I'm definitely interested in spending a lot of time with to see just how far I can progress. What I like about it is that it's essentially a self-balancing system that lets players eventually find their own level of racing, providing the perfect level of challenge for each player.
I pinched a snippet from the link. Multiplayer seems well structured.
