RP means medals medals means unlocking cars.
You're still presented with primary objectives that need to be met in order to progress further in the game, and there are also a series of extra ones that get you more RP, or in-game bounty. In Apex, you have a series of objectives to meet, with different rewards depending on what you do and how you do it. On the Xbox One, you'll be entered into race series and have to finish in a certain position to progress. This is where things deviate from the console version. As you progress, the cars become faster and more difficult to handle, while the objectives become harder to obtain. The career mode, if you want to call it that, is based around 12 "Tours of Motorsport." It's a series of circuits with different objectives raced in different vehicles. You can play on slower hardware by turning all the settings to low, and dropping the resolution to 720p, but it looks pretty bad. The problem is that you really want to be pushing for, or close to 1080p to get that proper Forza look. There aren't many settings to change, which is great for more casual players, but it would have been nice to give older PCs a chance at playing the game comfortably.
With a less powerful graphics card, I found a persistent message on screen letting me know that I was low on video memory when I tried to play at 1080p - and at several resolutions lower than that. If you try to push the hardware too far, the game does a good job of telling you to reign it in. The frame rate may not hit a consistent 60fps, but it rarely drops off with any noticeable effect, which is important.
I've been running Apex on a PC with an Intel Core i5 4430, 16GB of RAM and a Nvidia GTX 960 GPU, and I've been able to run at 1080p with all the graphical flourishes set to high without any real issues. Apex also boasts the same impressive weather and night racing effects as its console counterpart. Turn 10 uses a lot of sophisticated technology to scan the circuits in the game, leaving you with an accurate, highly realistic ribbon of tarmac. The circuits are the same exact models from the console game, so you get the same attention to detail. Overall, there are 60 cars to choose from and, sadly, only six circuits to drive them on. "While the marketplace tab exists as a way to introduce additional content to Forza Motorsport 6: Apex following the full release, we have nothing to announce at this time regarding post-launch support for add-ons." We asked Turn 10 for comment on what it's actually for:
There is a marketplace within the game, though it's not currently activated. However, everything can be unlocked - or so it appears - without the need to hand over any cash. If you want to unlock better cars earlier in the game, you can pay $0.99/£0.79 each to do so. It does have in-app purchases, but at least so far it seems perfectly possible to play through without hitting a paywall. As already mentioned, Forza 6: Apex is a free game.
