Forza 7 and Horizon 4 are on the Win10 store and they are very diverse driving experiences but its nowhere near any Gran Turismo ever.
Forza Horizon, maybe not. But Forza 7 very much flows in the same vein, Which is basically track racing. They have different approaches to it but they are very much comparable. It has been this way for the two since the inception of Forza. Going off what he's used to for GT, and what he's asking for, it's actually almost a perfect fit because of how similar they are at their core.
Horizon 4 is Horizon 3 in England and that's it. There's more fluff like clothes and emotes and buying real estate but its still the same "everything is a 3 lap race or its a point to point and its still supercars bouncing over rough ground like its a Hummer".
Well that's not a massive exaggeration
As for the game, you're right, the core idea is essentially the same. However, considering he hasn't played
any of them, it would make sense to not include that point as if it's actually going to affect him in anyway. So he should pick up the better and more polished of the two, which is the 4th entry.
Aside from that, all my races have been about 15-20 laps(because you're actually able to decide the length of the races between 3 selections, so might want to try to
not be misleading.) The vast majority of cars aren't supercars, but you're right that you can take any car anywhere you want. That's not a bad thing though, certainly not in the way you're trying to paint it, because
it's not a sim. Not on the level of GT and Forza Motorsport though, which are very much comparable and sit in the same spectrum.
Dont get me wrong... it was worth it just for an occasional laugh and I feel the $25 I paid for Horizon was ok for what I got but its certainly nowhere near GT Sport in conception or execution.
Well yeah, that's like pointing out night and day.
However, going off what the OP actually said, Forza 7 sounds like the perfect fit for him because of how similar it actually is at it's core. There are differences that you'd need to get used to
@Morethanwound, but it has 700+ vehicles, customization, and is a track-based racing game, and it's available on PC. I'm not sure if there's a demo out, but I'd recommend looking up videos if not.
