No it means that people thought car pricing was just retarded high, it can have nothing at all to do with the game being grindy. There's nothing in that link that specifically says the game is too long of a slog, we'll lower prices. It says we heard the feedback, here's 50% off car prices for now, we'll permanently fix pricing later.
Err what? The two are one and the same. Cars being priced ridiculously high == the game being too grindy. We are 'grinding' in order to purchase new cars. You can't separate them. Time == money, quite literally in this case.
Anyways, I finally got a chance to play it myself, and I am also completely disappointed with how they handled this.
The rewards are awesome, you get a ton of credits in a ton of ways, the core game loop is excellent, but the prices on the cars are INSANE! I played for 2 hours, earned close to 80,000 credits, and the only car I could buy was the crappiest, lamest little econobox. In the old Forza, I would've won 3 cars by now, be able to purchase something fairly exotic. Instead I'm still stuck with my original ride, and can't afford much better :/
They've added a permanent UI element to the screen "Press Y to Boost XP", so this is now in my face constantly, and in my 2nd circuit, when it was time to purchase a new car, one 1 of the 4 'recommended' options (the most interesting one, a vintage Toyota GT86), was marked DLC, when I clicked it it prompted me to buy it for $3. No option to buy with credits at all. Are you serious? After I just plopped down $60, and haven't even played for 2 hrs, you're already showing me restricted content?
This is a real shame, and a bit of a travesty for me personally, as this is one of my top 3 favorite franchises. Extremely dissapointed in Turn10, and they've lost a lot of my trust as a developer. I will no longer give them the benefit of my doubt.
I appreciate the fact that they are fixing it, but the fact they made these decisions the way they did, shows that their judgment is extremely questionable.
