Possibly unpopular opinion but i'm not a fan of them changing the layout on legacy tracks, unless there's at least a proper classic version of the track in the game alongside it. Really don't like that they removed the fast start/finish straight chicane to a slow one from the looks of it. The map being upside down is also triggering me a bit.
Everything else looks fairly promising I guess, but i'm waiting to see the full game to see how I feel about it. Still never bought Sport as i'm not keen on the always online saves, once that server goes that game is useless.
