ModNation Racers's track editor won't even be possible on the PS4. By then, GT6/7 will be way too graphically superior for that possibility. I thought that was obvious.
I hope it can be a mixture of both. I want to be able to generate a track quickly enough, then be able to fine tune it some and in separate, specifically chosen sections. It would obviously help to speed the process up and for people like me, who don't know completely what makes a track good, to have a amateur/beginners process so it feels more welcoming.
Basically, have it so that you can create a track from scratch and precisely choose all that's possible right off the bat, or have it be like the way I explained above. It wouldn't even need to be labeled "For Beginners" since it's more of a way to speed up the whole process and more efficiently for a lot of people.
