Yeah, they seem like silly complaints to me. The car levelling system seems like a great idea, I haven't played that much yet, but what I have played seems less grindy than past Forza Motorsport games to me, because you no longer have a shared credit pool and therefore can put your credits entirely into cars while upgrades come from a separate money pool you earn by using that car. Just from doing a single 3 race circuit I had my first car upgraded a good bit. I can only assume those that are complaining about the grind are comparing it to Forza Horizon, which gives out free cars and free money like candy via the frequently earned wheel spins and super wheel spins.

Forza Motorsport doesn't even seem half as grindy at launch to me as GT7 supposedly was, GT7 was heavily criticized by the fans for it's grindiness, with reports of dozens of hours of playtime just to earn enough in-game credits to buy the most expensive cars which cost 3-4m credits each (which Sony clearly implemented to try and force people to buy the most expensive cars with real money, some of which costed over $40 for a single car). They later patched GT7 to double credit earning speed, but only after critics saw that extreme level of grindiness on launch and still gave GT7 an 87 average on meta. Now those same critics complain about the grind in the far less grindy Forza and ended up giving it a lower meta score, it just doesn't make sense to me. 

Lmao. Nvm.

Yeah I'm not really getting the grindy complaints about Forza at all, just did a single race on Watkins Glen and got over 14,000 credits, and I'm only on 4/10 on difficulty and the simulation tier that gives you the least money per race, if you're playing on a higher difficulty with full damage, tire, and fuel simulation you would get over 20,000 credits for that race I believe. And I'm only on the 2nd campaign, I would assume later campaigns pay better rates. I just don't foresee any issues being unable to afford to buy a car that I want for each campaign/circuit, and that car you pick for that circuit will level pretty quickly if you'e good at racing and get good segment scores frequently like I do.

I will say that I have found a few things about Forza Motorsport that I don't like, though ironically none of them seem to be things that the 5.5-7.5/10 scoring critics complain about:

1. Where is the music? I remember fantastic in-race music in some of the past Forza Motorsport games like Motorsport 5, but there is only music in menus in this Forza. This was probably done to really bring home the racing sim aspect, since real racers aren't listening to music in a race, but turning music off should have been an options screen thing rather than a forced decision by Turn 10.
2. The UI could be better, I didn't see a way to download and apply sprays when buying a new car needed for a circuit, instead you have to back all the way back out to the main menu and go into a car menu there to search for sprays. On top of that the actual download and installation of said sprays is slow, roughly 20 seconds per spray. 
3. The rainy tracks don't look as good as I remember them looking in Motorsport 6 and 7, I remember huge puddles that realistically pooled in low elevation areas of the track, but the only rain race I have done so far had no puddles, just basic wet asphalt that seemed more like Gran Turismo games than the fantastic wet track system of Motorsport 6 and 7. 

get rekt lmao. 

I still miss Gamer's Club Unlocked, that was the best deal in gaming (before Gamepass)

LOL, imagine thinking Gamer's club is better than gamepass. 

Dude, u should work for some politics site I swear to GOD imma have Ryuu spank you extra hard if you keep this up

Looks like it is a strong possibility:

CEO of Limited Run Games. I think Xbox goofed by pushing the digital only Series S as hard as they did, losing retail shelf presence would be a huge blow to Xbox, shelf presence is basically free marketing, free marketing that is particularly useful for winning casuals.

It's happening boys:
