Here's my feedback after 2 weeks on this game, casual but sometimes have 1-2 hours sessions [TIPS FOR BEGINNERS AT THE END] :
I managed to get top time in [Uphill-3-2-A], starting to get the hang of it :D
-Nowhere near boredom : The game offers plenty of cars, and there are "technically" 72 different tracks
-The xp is quite long to get : At some point, I can keep restarting the tracks as soon as I damage my car or miss a drift, which means I can easily spend more than 30 minutes without reaching the end. Plus, the different cars are only cosmetics... Maybe it would be fun to give different stats to each car, and make a different leaderboard category for each of them?
-Unfortunately, there's quite few competition, as many leaderboards don't have much more than 10 players registered... Although there're always really clean high scores, often by goats like Hima or Swat.
Tips for beginners :
-Downhill / first world / first road [D-1-1] feels really hard ; Toreno isn't the easiest to handle and nasty turns don't help. Seeing my platinum medals, I'd suggest starting with Uphill / first world / first road [U-1-1]. FCD is less sensitive, which allows better control to learn the physics for newcomers.
U-3-2 also seemed to be especialy easier to me.
-My personal tier list of types, from easiest to hardest : FCD - Toreno - Muscle - Carscherra - Kenernbilt[Truck]. The non-driftable types are all harder imo, as they leave you no choice but to manage speed with an extreme precision to take turns.
-My best key to get a high score is to spot turns where I don't need to drift. There are quite many, and even though it's harder to achieve, sticking on the track when possible is a must for high score.
-Pressing left/right doesn't instantly turn the car : It "slowly" turns the wheel, which means turning to max left can require to press [left] for ~1 second. This means it's often required to start steering as early as possible
-Since drifting eats up speed, I use to start steering as soon as possible (so I already get partially engaged into the turn), then hitting the brake as late as possible.
-To take a turn that necessites drifting, I approach it at large as possible, and when I'm in, I try to keep my bumper as close as possible to the interior barrier to optimize the turn.
