I really haven't played GT7 much over the last few months, but picked it up again over the last week following the physics update.
Over the last few days I've kicked myself for not doing the Track Experience challenges previously, as the new physics make them more challenging, and I'm questioning if the ghosts/times were adjusted when the new physics were implemented (I don't think they were), as it appears the GR3 cars are braking way later than I can and not having understeer issues while doing so.
I pulled a Lexus LFA from a ticket late last week and threw it around. Completed this week's challenges last night for the 6-star car ticket... and pulled another Lexus LFA. Promptly sold for just under a million credits. The humor of the LFA for me is that the other game I'm splitting my time with, The First Descendant, is also an RNG hell-hole where you'll grind for an "amorphous material" aka loot box with 5 possible rewards, to then have to grind out a boss battle to open the amorphous material, just to get exactly what you don't want or something that you've already got 20 of. Sometimes this can be a 20-30 minute process depending on what you have to do to acquire the amorphous material.
RNG. What a blessing that was when it was bestowed on videogames!
