Have you played WRC 6? Then you've played WRC 7. Besides a boost in graphical fidelity, it's almost the exact same game and even some of the courses are repeats. I know that it's modeled after the 2017 WRC course maps but you'd think a conglomerate as big as the FIA could afford to change things up year after year.
Regardless of that, it's a very solid and welcoming racing game with varying degrees of difficulty and assistance that allows everyone to enjoy it. You can go full speed with arcade physics and zero damage or toughen up with simulation physics and irreparable damage. Even after you get comfortable with your own play style the game still throws challenges at you with changing terrains, weather, and gorgeous scenery you wish you could stop for a minute to take in. Pace notes are precise and a lack of attention on part of the player is the only fault for going off-course. There's a wide variety of locales and a long career mode that takes you through all of them. The only thing this game is missing are cars from the past; if they added that feature to future games it would be the ultimate rally racing series.
If you're a fan of sim racing games or simply curious about the hype behind rally racing, I implore you to get this game as soon as it goes on sale. Since it's just a rehash, it's not really worth the full asking price.
