This should not be a question, its pretty clear INI file system is meant for intializing not to be used as some sort of database. E.g. you can store server settings in your ini file and then parse them from the ini file into an array for runtime usage, when your gamemode starts.

MySQL on other hand, can be used as a user database, personal vehicles, etc. With better speed and ability to read/write/update multiple rows with complex condition statements.
