Even on GTPlanet, there's a huge thread in which Forza Motorsport 4 is regarded as the more realistic as the two and by all accounts, Forza 5 is even more realistic than Forza 4. GT6 still didn't fix issues like the poor tire physics, poor torque steer and total lack of sidestep. So no, GT's physics are not better than Forza's. Not at all.
Yeah, that's why GT5 was so much better than Forza Motorsport 4, right, because it had almost 500 more cars? Oh, right. Forza 4 outscored it virtually everywhere. Quality is better than quantity every time.
Quality > Quantity. Gran Turismo still has almost a thousand poorly modeled standard cars, terrible audio, even worse damage than GT5's practically non existent damage modeling, mediocre weather and rally, no liveries and a host of other issues.
Besides, Forget Forza 5, GT6 is still competing with Forza 4, which was far, far better than GT5, even with less cars and tracks.
<< LINK REMOVED >> Realize that quality is more important than quantity, ditch standard cars completely and rebuild them from the ground up, even if they have to outsource some of the rendering jobs. Turn 10 did it, so can Polyphony Digital. Add in proper damage modeling, and for the love of all things holy, fix the audio. Gran Turismo's audio sounds like it was recorded in 1997 and never updated.
Or, you know, they could fix the game's economy to remove the grind without steering people towards microtransactions. Leaving the grind in and saying "Hey, you can always just pay us some real money if you don't want to grind!" is not a good alternative.
Meh. This seems like GT5.5 to me rather than a full sequel. From what I've read in the other reviews of GT6, it's brimming with content but it lacks polish, just like GT5 did and they still haven't fixed the AI, the terrible audio and haven't added a capable damage model.
Oh well. Seems Forza 4's last gen racing sim superiority will not be challenged by this one.
