The author makes the accusation on live service hell twice but doesn't seem to actually give any basis to this besides "it takes a long time to unlock the best stuff in the game".
I did not realize this game is being made by KT Racing. Their WRC games were kind of yearly copy/pastes and the last one had around two months of updates before it was abandoned.
I won't dismiss this game yet but it has me a bit worried.
I played a lot of the old TDU and the Nacon WRC Games. Long story short, the way they handled Generations, that was supposed to be their last hurrah with the franchise, was so bad, that I completely gave up hope on Solar Crown being good. And I've been having the live service hell feelings about it for a while too.
