I don't think it would hurt their business too much to release FM6 with less cars and WAY more tracks. Instead of releasing DLC tracks, they should focus on DLC cars. Free would be good, even if it isn't, people would get it.
Variable weather and day/night should finally make it into the game, with the option to speed up or slow down the transition, ala PCARS.
We should get more upgrade options... i.e. more parts from different manufacturers and puh-leeese give us MORE rims and bodykits.
Cockpit should have more interactivity. Controls for traction control on/off and all the other goodies race and road cars come with. Toggling vipers on/off, headlights lo/hi beam etc. Sport mode, race mode and so on. You get the idea.
We....must... have.... pit stops by now, along with real-life tyre wear and fuel usage. Why in blazes can't we select how much fuel to start the race with? It affects performance and handling characteristics.
Practice, qualifying and warm up/rolling starts. Especially qualifying. It's about damn time!
Make the replays 60 fps please, thank you. Not all of us own 60+ Hz screens, and have no intentions of upgrading either. And T10... you really need to invest into some good replay cam angles. 5 games now, you couldn't get it right.
Suspension and brake modeling should be given as much attention as tyre physics. Also focus more on aero physics. And for God's sakes, get rid of speed sensitive steering on controllers!
Sound must be taken to the next level. I think the hardware is here now. All that's needed is some creative thinking and innovation.
It probably wouldn't kill the devs to have an option for assigning individual buttons on a controller, rather than making do with different defaults. Steering sensitivity option must be given. It must!
Tire smoke... you got the graphics right T10...the sound.. the physics... why are the tire smoke effects SO lame? I've never seen a race or video where the wheels lose traction.. and the track farts up puffs of smoke a second or two later..
Still waiting mate..
