7. Just best all round package. Started off rather rough with its micro transactions, was fixed and game has come good ever since.... Kinda the theme of xbox in general last generation. Only started playing once I got my series x. 4k 60 in all its unwavering glory.
I expect big things from 8. Longest dev time, new engine and they seem to want to launch the game and have substantial updates moving forward as a Gamepass incentive.
As one of the "big 3" it certainly has the pull to draw and keep people in. The consensus among critics seem to put Forza series above... Umm... That other racing game in recent years, largely due to horizon though, to be fair.
As a pillar title, I expect turn 10 and MS to turn it up to 11.
