So, I was just thinking that I have a 95% completion on the championship with all the cups beaten. I guess I'd have to achieve gold in every of them to get that 100%. I don't think it's possible with that Desert race. It's just a pain in the ass.

Well here is the thin silver lining with that desert course: the AI suxk at it too.  So pick a vehicle with tight handling that you can get first in the other races in and take that desert course decently slow.  Use the break (even letting go of the acceleration) on the dangerous turns.  You won't win but you should place above 10 if you don't let yourself crash.  However, even if you do place 10 the rankings on that track are usually chaos so it might not hurt your ranking too much.  You'll just have to win the last race the clinch it.

I managed to get a 6th once, but it's hard as nails. I'm using the supposedly "worst" car in the game, but I think that using high speed and aceleration cars in Hypersonic could get you destroyed. They're hard to keep on track. And this car is easier to handle (that car with the teddy bear in). So far I get better results, but I don't beat the silver. I guess I'll just keep trying. Which cars are you using?

With Sunahara Desert I just drive slowly and carefully, using Ziro for its tight turning, get about 6th, then win the cup overall by placing well on the other three tracks.

I use Muellers and Rochdale.  However, I don't know if you have those yet.  Ziro is something approximately similar to Rochdale.

To get all the cars, do you need to beat every cup on Supersonic?

Clearing cups unlocks vehicles all the way through the first cup in Hypersonic.

I hope they mention something about FRN then. Btw I also saw in the eshop ranking that Trine 2 is actually the most downloaded wiiu game ever here in Spain O_o above Wind Waker HD. That sounds like a pretty great success here, I´m surprised.

I finished Subsonic with all gold. However what's up with the rankings? World record times are 4 minutes? Is that for Hypersonic? My times are in the 10 minute range for Subsonic.

The random crap with huge setbacks as a result is a bit annoying, I guess without it the game would be over too soon. Still not fun to get hit by a random fire ball in the last lap or bumped off the track by the AI in a turn and go from first to 8th. I guess rubber band AI will never go away. Best to save boost for the last lap, as they'll slingshot past otherwise. I've come in third with much faster times, than when biding my time and going all out in the last lap, placing first with a slower overall time.

Anyway it's smooth, short load times, keeps it fun to try again.

There will be an update in January adding some new features and fixes:
