My son is a big fan of the game. How best does he request features?
1. Engine options when buying cars from central.
2. Soft body crash physics (take notes from BeamNG or the Matrix Awakens).
3. If you could add a long stretch of motorway to Tokyo Express Way.
4. Add a BMW 635D
5. Customisable body kits (should cost 100k) where you can change the width, height, lights.
I'll give my thoughts on this but some will be simply repeating what
@UltimateYosh has said just above.
1. That's possible and would be neat, but it's more work than simply having each option availalbe as it's own seperate car which also boosts the car count. PD aren't going to suddenlty instert this into the game though.
2. This simply won't happen, if you want that level of damage you need a game that has fictional cars, manufacturers in general simply won't agree to let their cars be smashed up like that in a game as part of thier license.
3. GT6 has a track a bit like that, it's a very long, mostly straight highway. I don't see PD creating this track,the longest route of Tokyo Expressway is the best you're son is likely to get in GT7.
4. Very specific and as a result unlikely to appear.
5. This is possible and I would like to see it happen, but it would require changes to other mechancis too, such as wheel offset which would also need to be a dynamic scale rather than pre-set widths.
There's no direct channel to pass feedback on to PD, the best you can do is here, Twitter etc. but beare in mind it took mass review bombing to get PD to make a change so people could earn Cr faster in GT7 so hey aren't prone to acknowledging feedback in general. That's not to say they take no notice, you'll just never know if they've done something becuase they've seen it suggested unless they psecifically confirm that.
