So this is Forza 5 released in 2013 and still hasn't lost its charm.
Basically, Forza 5 is a grand tour through motoring both present and historic. You race slow cars, you race fast cars, you race new cars, you race old cars and you can race just about any car as you progress through career with a bit of education along the way.
I played this on the Xbox One. The interesting thing is that the Xbox One is semi-4K meaning there are features of the game such as the crowd and reverse view which are in 4K. But this is not a complete 4K game so make no mistake. Microsoft does not support a 4K Forza 5 on the Xbox One X.
This game has aged well it is still a lot of fun if you tend to be rather good at driving/racing games like myself.
You can adjust different settings such as car ware and tear and remove guidelines such as braking before sharp corners. The more you play like a pro the more credits you will be rewarded with to buy and upgrade cars.
Before I played Forza 5 I thought about buying a steering wheel, manual gear stick and pedal set to make my gaming experience more realistic. Don't. Don't because what I found is the heads up display suited me just fine. You can play this instalment of Forza 5 in different views but the best I found was the steering wheel and dashboard view. Playing at a computer desk with a decent gaming monitor also helps you. I game with a BenQ gaming monitor an American product which is arguably the best for HDMI and semi-4K gaming. BenQ has a reputation as being what it is because their hardware is used by the best gamers in the world. Also, don't buy a full 4K ultra HD television just buy a 4K gaming monitor and set it up on a cheap computer desk which you can assemble (two people is best) and sit in front of it with your undivided attention.
So these days Forza 5 would be like about twenty dollars from EB Games or anywhere else for that matter.
Just buy it give it a go and have fun on the track.
