Hej. I just registered here to ask this question. I have been wondering, having recently begun playing the first iteration of the series, which is the hardest one. More specifically, which one makes it the hardest to obtain gold trophies in the license tests. ??? Also, thanks to https://www.gtplanet.net/forum/showthread.php?t=113495 which thread was returned from a search-engine request, and informed me about the existence of this forum.
