I've taken the opportunity to play some arcade races offline over the last couple of days but there's even some question marks about that.
Firstly, my game actually froze after just one race yesterday, which was the third time since launch that it has happened, but is also pretty poor given that this is literally all we can do with the game (except for the mind-numbingly awful Music Rally).
Yesterday, the distance I raced was credited in the usual manner toward my Daily Marathon goal (which I was surprised to see), but that has not happened today. It remains to be seen when the servers come back up whether or not I'll get these two Daily Marathons (and the associated roulette tickets) credited to my account, or if they will just vanish.
Arcade Mode has always been a bit borked, and while I enjoy it to some extent, the rubber banding is frankly ridiculous. And that is with the 'Boost' option turned off too. My last race was 5 laps at Fuji Speedway on Expert difficulty. The lead/pole car did the first lap some 11 seconds quicker than me, and yet I managed to finish 2nd, just 2.5 seconds off the lead. During Laps 2-5, I was consistently lapping within a one second boundary, but even my quickest lap was still around 3 seconds off the purple lap set by the pole sitter on Lap 1 which ought to have been his
slowest lap, not his fastest by a mile.
So, given that this is all that is currently on offer from GT7, it is pretty disappointing.
edit: Aaaaand it's frozen again...
