I recently found that the credits of Chocobo Tales vary in length depending on the version of the game: JP takes 9:47, NA takes 11:42 and EU takes 13:14. In light of this, I asked Crrool for his opinion on what should be done about timing in light of this, and I also asked the wider speedrunning community for their input since this isn't a popular speedgame (https://www.speedrun.com/speedrunning/thread/5idsy). Crrool and I shared the opinion that since the credits are purely an autoscroller in Any%, it would be a better reflection of each run if timing were changed from IGT to RTA, ending right before the credits began to roll. I enacted this change today, and all Any% runs will be timed in this way from now on.
Note that for 100% Collection, since the credits are an important gameplay segment in that category, timing remains unchanged. If you want an optimal 100% run, it is suggested that you run on the Japanese version of the game.
