Man, I wish I picked up this game earlier and could have experienced all of these grand prixes as they happened. This game has been a family event but it seems that support might be dwindling this far out from release. Not commenting on this latest grand prix, just a fear that we may have caught up to their pre-release head start so to speak.
I wonder if a Rocket League approach could work for them in the future. A season pass spanning a couple months of cosmetic add-ons (decals, stickers, paints, skin colors of multiple skins etc) with a seasonal grand prix to mark certain holidays or seasons with a new track, characters, cars and legendary skins as it is now. Meaning these maybe happen 4 or 5 times a year with the lesser stuff being more steady (but still cool to get alternate colors of legendary skins)
