Nope, I have only played every Forza game that has been released. As for the grammar and spelling mistakes, that's why we have an editor. As a writer, it is sometimes hard to find mistakes, even when you look over your work multiple times.
The constant comparison to Horizon is because that game shows how you can take the Forza gameplay, add some atmosphere and life, and make a great game. Forza 5 completely lacks the latter. Sorry if I don't praise every single Forza Motorsport game that releases.
