FFTA2 and probably some other final fantasy games use the term magick. It's just like regular magic, but the k makes it more kool, because.... Reasons. I found it so annoying to see magic spelled that way. Every. Single. Time. It's just incredibly unnecessary and feels lazy. The silver medal goes to using the term hume to describe a human. Once again, lazy and unnecessary. The icing on the cake is that the first final fantasy tactics advance just used the regular terms, so there was no precedence set to use those replacements.
