Square-Enix had a tough time adapting Seiken Densetsu 3's event scenes into 3D cut-scenes in Trials of Mana

Square-Enix has really put their all into Trials of Mana. They took the original Seiken Densetsu 3 and translated that 2D experience into a 3D polygonal game for today's audiences. The entire project took a lot of hard work, but in an interview with Nintendo Life, producer Shinichi Tatsuke said adapting the event scenes from the Super Famicom release were especially challenging.

The event scenes in the original game pushed the 2D graphics technology that we had at the time to its limits, but when we came to bring it into 3D using today’s technology, we had to use our imaginations to create some of the things like facial expressions and motions that were difficult to express back then. Doing that was quite tough, and in some scenes, we had to add in a few new lines of dialogue or extend character performances. You might notice some things if you compare it to the original game.
