The problem of the game is that it relies too much on FOMO. It has been discussed all over the forums what the problems are.
If new players could play all previous FOMO SP content PERMANENTLY, then the game would sell much better I am sure of that. Yes it isn’t that much, but it would still change the overall “feel” of the game.
The formula of adding and removing content in this game simply doesn’t work, they have to remove the remove part of it lol and only keep adding content in SP.
This sort of FOMO like it is now, works perfectly fine in an Open World game like Forza Horizon, but not in the Motorsport series.
