This very quickly went from “this is a decent selection of cars” to “this is the worst update yet”.
Seriously, what is so hard about adding more races in each update? It’s basically just a spreadsheet and photoshop work if there’s a new card, maybe some time in the livery editor to get some unique AI opponents. Just something that’s more difficult, longer, and/or has more strict entry requirements. Anything structured to encourage exploring the content being added (and already existing) in the game.
