I've found I do as I'm used to what I thought

I know that it's "Tee-dah" for example but when I read it I often find myself saying "Tide-uss" and I dunno why... The same goes for Cid I still pronounce it "Sid"

A strange one though is when I was younger and was reading stuff about FFVII (My first FF) and when I got it I kept say Midgar as it had soft "G"... Like "Midd-jar" or something.

Obviously I soon realixed it was wrong. But Even to day when I play FFVII on my on I somtimes say "Midd-jar"....
