The subject of microtransactions also came up in the session, with Esaki confirming that there would be no cash-for-currency MTXs in the game. Of course there’s a car pass, welcome pack, and race day car pack available at extra cost over the base game — all included in the Premium version — and a VIP membership which includes cars, vanity items, and a permanent credit multiplier.
From the article:
I don't think DLC for extra content and pre-order bonuses count as microtransactions.
