Had a lot of fun with both Horizon 4 & 5, great mix of arcade and sim. Tons of cars, just about everything is viable. Lots of accessibility options, should be a good fit for just about anyone.
Forza Motorsport (2023) on the other hand is a massive disappointment. Avoid. Driving dynamics are good and more simmy, but everything else is a downgrade from its 7 year old predecessor. Kind of amazing how terrible it is. Apparently Microsoft had developers constantly rotating out on short contracts and it shows.
