You can’t poison this thread with Xbox shenanigans! =P
But yeah, as long I have my place guaranteed I’m not too fussed who else is in it provided fair racing is maintained. There were a few “guests” in Season 1 that were a bit aggressive so apart from the original participants any “new” members would have to have trial runs with constructive feedback.
Of course the season is a long way away so it’s best to not sort anything out until a few weeks before the game is released.
