That of course depends on the game you're giving the accolade to... I happened to think GT4 is the best in its series and still think DMC 1 is the best in its series and you will know there are people out there who hold up Zelda 64 and Mario 64 as the best games ever and the best entries in their series, despite them being over 20 years old
I happen to think the racing and handling in Forza 8 is the best in the series, love the dynamic weather and time of day and the graphics look sensational.
My issue was with the boring singleplayer layout and its terrible presentation and menu graphics
It was a massive step up over Forza 5 and 7, but Forza 6 remains my fav in the Series, but as I said I found GT 7 and Forza 8 to pale to Codemasters Grid Legends
