They need to do something about this falsely-advertised, 🤬 AI. It doesn't matter the difficulty, it drives no different than it ever has.
I think it's actually worse than the FH5 AI in terms of how "hitty" it is, but their pace is definitely faster than any previous Forza game and you don't have the silly rubber banding of FH5. You can defend your lead ahead of them, and what works when doing that is similar to what you'd have to do against a human - position inside the driving line on corner approach then take a shallower line under braking. Most of the time, the AI will stay behind you and not hit you if you do that.
Overall, the AI falls way short of the hype of the live stream, but IMO it is nonetheless a clear improvement on past Forza games. I'm able to enjoy the tour series on max difficulty starting from 12th whereas unbeatable in previous games has generally been very easy for me, though unbeatable in FH5 can be fast for some races, but it's a fake pace. The FM AI often still has a small number of places on a track where it's obviously bad, e.g. braking in a flat out bend. If they improve it to fix those errors, it will be extremely fast.
An example of the AI working well, I went into the MX5 series with a level 1 car, so my upgrade options were limited. I blasted from 12th to 1st in the first straight, as my car had worse tyres but more power compared to the AI. It was then a genuine battle lap after lap to keep the 2nd place AI behind me, as I pulled away a bit on each straight, but it threatened to overtake me on every corner if I didn't defend properly. I can honestly say I've never experienced races like this in any previous Forza game. This was max AI difficulty. (My driver level is bugged, I think it might have happened when I restarted a tour series).
Played it for an hour or so this morning.
First initial impression isn’t great unfortunately.
.....
I expected more because of the reboot nature of it, the huge amount of time they took and the marketing.
Will certainly play it more and give updated thoughts on it should they change.
Give it more time. I refunded the game on Steam I was so unhappy with it, but then I bought it again, and have become happy with it. It needs a lot of work, and is nowhere near matching the hype, but it's an acceptable product (a clear product of the "minimum viable product" approach to getting a game out of the door), and distinctly better than FM7. The only element I truly hate now is the stupid car levelling system. I don't care if some people like it, I can't believe that a large proportion of the player base is going to like having to spend hours levelling up each individual car before they can use it properly (only 7% of players have currently levelled a car to level 50). Yes you can have the game level a car up for you while you do something else, but even that gets really tedious after a car or two.
Another thing I'll add is everyone should try the first person cameras in FM. I've always preferred chase cam in Forza, but there seems to be something different about FM's physics that makes everything feel so much better with a first person camera.
