2nd playthrough and I don't remember this being as good as it was. Again, maybe just my FH4 bias, but I had nothing but a good time playing through this again.
The occasional storms were nowhere near as annoying as the blizzards in 3's expansion, the progression felt good with better rewards (1mil for finding a treasure chest each round and some new to this DLC cars with some of them), all good races and stunts, really good map for what it set out to do, new drift story (which I really appreciate since I love drifting in this, and no overly bs bonus boards or anything. It's just solid. More FH4 with the addition of that story I mentioned, treasure chests, and trailblazers.
Treasure chests and trailblazers did come back in 5, but the chest in 5 are just to progress towards the latest Forzathon car and don't give much of a reward. And then the trailblazers in 5 also just didn't feel as good as they did here. Really nailed it their first time with them. Still, it seems the drift road in this really inspired them to give us better drift roads (like the mountain) in 5. So that's something.
Great vibes in this expansion all around, not too long either.
