Double post, apologies.
One thing I will say, a lot of the complaints that come from everyone is just bitching (IMO) yes they are justified complaints and rightly so because a lot of the decisions are stupid! But when it comes down to it, the actual 'in-game racing' is a massive step up from Forza 5.
Yes some big balls have been dropped, but the actual atmosphere, graphics, physics and sound, god the SOUND cannot be praised enough!
Oh and I agree. I fucking love the visuals, physics and sound. It's just a complete package in that regard.
The tyre and suspension model is simply astounding. So much more going on than previously. Every phenomenon feels realistic(over/under/torque steer..etc), and behaves as you would expect. Weight transfer is not only better in the way it feels and behaves, but it looks so much better too. Kerbs and the different surfaces all interact with you car amazingly well.
It seems that characteristics and behaviors pertaining to a particular car have been brought forward faithfully. The car's default factory settings are also much more realistic than before too.
It really is a satisfyingly good physics model Turn 10 have come up with.
Then you have the ever faithful upgrades, customization and tuning options. Very deep as always. Very comprehensive. Sure, even more more can be included., however, as it stands, you have a great array of performance upgrades to install and tune. Engine swaps, cam and turbo upgrades, bodykits, wheels..etc and amazing painting system. Gearing, tyre pressures, brake bias, spring rates,differential adjustments..etc....it's all there to indulge in 'till your hearts content. The paint in particular looks amazing in FM5.
The you have that glorious sound. Almost every aspect of the audio has been dramatically improved upon. Sound is usually talked about in regards to engine and exhaust notes. While FM5 certainly has trounced that part from previous games, it's always more than that. You have the turbo spools. You have the blow off valve's. You have supercharger whine of the twin screw and centrifugal varieties. You have trans whine. Not only that, those samples aren't just some generic 'whoosh' or something. Different cars have different spools. Different cars have different BOV's. There's more though. Then you get into the upgrades. Each and every 'stage' delivers even more new sound samples. So at various 'stages' you get different BOV's. Not only that, but it's also pressure sensitive and even then, the sounds behave differently too. Then you have weight reduction enhancements where stripping out the interior's sound insulation results in a more louder and aggressive cockpit.
Then you have the physics induced shifting effects from driveline flex. Shifts sound so much better now as if a human has shifted and not some robot.
Then you have the backfires and exhaust rumbles which get even more aggressive as exhausts and cams are upgraded.
Then you have the spatial sound improvement where cars can now be easily distinguished depending on their position. Interaction with other sounds as well of course. It was a much needed improvement.
Then you have suspension/chassis noise. You have cockpit filters. You have an amazing reverb system that isn't limited to tunnels. Noise bounces off most things and that's simulated in FM5. Then you have the exquisite tyre sounds. From the scrubbing at slow turns to the screech of complete grip loss. Then you have the ambiance of the crowds from their glorious cheers and whistling as you pass pit straight through to the whirling blades of the helicopters above.
Having that 455 Big Block growl angrily at you as reach for 3rd or that beautiful straight six at 7 thousand rpm's as you get ready to drop down a gear or two, from that sensuous scream of the LFA V10 as you pass through the tunnels of The Alps, to that addictive whistle from the turbo, and the subsequent 'tututututushh' from the sequential blow off from the RX7....it all adds up to a tremendous driving experience and would send chills down any sane persons spine...
Obviously, tracks, cars and other features are sorely needed but as it stands now, even with less content, you have a great package on your hands as a racer....physics, sounds, visuals, AI, customization...yeah, I can live with that for now....
for now..
