I got this given it´s extremely cheap on the argentinean Xbox store (some $2).
I love Dirt Rally 1 and 2, I despised Dirt 5, and IMHO the WRC series has been slowly getting better, particularly at tracks. I remember than WRC6 and WRC7 beat Dirt Rally 1 in that regard: the scenarios were more organic, more realistic.
I skipped WRC 8.
WRC9 is another small step in that evolution. Technically, it is rough: on my Xbox One X, it looks humble and doesn´t run smoothly, particularly compared to Dirt Rally 2. But the carreer mode is very interesting, there is a lot of content (even legendary cars!), and I plowed through Junior and WRC3 during the weekend. Fun, well made game.
I wonder about the future of the series now that Codemasters aquired the official WRC license...
