I loved the Trails games, unfortunately they lost me mid Cold Steel 4 (Cold Steel 3 was already cumbersome to end for me). Too many sudden appearances of past games characters to save the day/prevent Rean from using that. That and eveyone saying "oh, silly Rean, always overworking yourself to help others" while Rean awkwardly scratches the back of his neck, eyes closed while he smiles. Too much for me.
I think the target audience changed during the Cold Steel games and I wasn't part of it anymore.
