First off, there is a
ZD suggestions thread where you can make suggestions like this. Please do not make threads for forum questions or concerns; either post in the aforementioned thread or PM a moderator/super moderator.
Second, the prefix system allows each of the main Zelda boards to be easily organized, whereby if you click a prefix, only threads with that prefix will be displayed. For example, if you go to Classic Zelda and click the bolded Majora's Mask prefix in front of any MM thread, only MM threads will be displayed. OoT had its own board due to the remake. There are no plans to give individual forums to any other games right now.
