I'm always happy to play more Forza Horizon, even though I feel the DLCs don't ever reach the same heights as the main game.
The important thing to understand is that despite the Hot Wheels licensing, this is still very much a Forza Horizon game and not the other way around. While the map is blissfully Hot Wheels with its orange track, loops, and spirals, the Forza Horizon physics haven't changed. The Hot Wheels cars don't handle much differently than the real cars in the game. This isn't a bad thing, but it is notable.
If you are looking for more of an arcade Hot Wheels experience, the Hot Wheels Unleashed games might be a better bet. That said, if you're just looking for more Forza Horizon content, you can't really go wrong here.
