I can't answer for bad spelling. I have an A-grade English A-level. The average reading comprehension age in the UK amongst adults is that of an educated 9-year old (BBC results). Spelling is worse thanks to Microsoft spellcheckers (usually defaulting to US Websters ). The game itself uses the American spelling for sales purposes. No biggie. I'm telling you that it is "Mediaeval" - meaning "Media" (middle) "Eval" (age) in English.
