First of all, "Horizon 4" and "Horizon 5" are both very playable and classic racing games, and you can play them both. If the budget is limited, then play 4, because it was released a long time ago and the price is relatively cheap. At the same time, "Horizon 4" is set in England, while "Horizon 5" was filmed in Brazil, so if you want to experience the English style of snowy winter, please play "Horizon 4". If you want to experience tropical waves and other elements, please play Horizon 5. The vehicles in "Horizon 4" will not be carried over to "Horizon 5", so if you have played a certain game for a long time. Just keep playing and don't change it unless you want to experience it further. Because the two games are very similar overall, there is not much difference, except for some screen optimization.
The exhibition matches in "Horizon 4" are more abundant because the update is relatively complete, while "Horizon 5" is still being updated. Horizon 4 has three small pictures, while Horizon 5 has only one large picture. At the same time, the "Forza Horizon 4" championship is still being updated, but there will be no new cars. If you have a collecting habit, please play 4. If you want to follow in the footsteps of the previous version, then play "Forza Horizon 5". In terms of operating feel, the operating feel of Horizon 4 is relatively stiff and not as smooth as Horizon 5. However, if it is just a casual player, generally speaking, it will not have a big impact.
