The narrow-mindedness is strong on this both side of the forum.
You mean...
Anyway, I really dig threads like this, especially when they're mostly flamebait free. While I'd include a few tidbits from the latest crop of PC sims, and most of the previous post's suggestions are worthy, I'll focus on a few things.
Physics. While I love GT6's physics and car dynamics, there is a certain quality in Forza 4 that is only rivaled by Live For Speed. Can't comment on iRenting as I haven't tried it yet, but I've seen car behavior in F4 that I haven't seen on much lauded PC sims. It's not perfect, but they did something right. And the tire sounds are spectacular, though I could live without the distorted Borla samples on every stock car.
Modifications. Oh yes, Forza is deep. Being able to bump a car's performance by selecting grades of electronics, fuel system and plugs, who wouldn't want to tinker with that if you could? Rim size as well as width for tires. Engine and drivetrain swaps... sure, why not? The selection of aero parts could be better, but it's far better than what we have in GT6 right now, though an update could change that completely. The mod system in Forza is essentially a Race Mod for every car. Which brings me to...
Livery Editor. Haters, get over it. Every pro racer gets to define his car with a custom livery, and to me, this is the one thing that puts Forza in the "gotta have it" category. I spent more time in Forza making race cars than I did racing, and that's not a bad thing. If you really can't stand to see cool custom liveries, just select
Hide Custom Liveries in your online options, and you'll never have to see an awesome ride ever. I REALLY MISS this capability in Gran Turismo, and hope we get it and possibly Race Mod back in one of these updates, though GT6 goes very far in that direction with its own customizations. And when we get a substantial online update, custom liveries aren't necessarily going to be essential, but will be darn close to it. I have a post I really should complete on this topic.
Leaderboards. 'Nuff said.
And I would like to incorporate almost every car from Forza 4 in GT6's car list, along with all the classic cars from all previous Gran Turismos, but that's another story. But between the two series, give me Gran Turismo's car list any day. And by the way, the bots in Forza are reckless tards.
