Engrish makes me cry.
And, I do recommend playing Ar Tonelico 1 and reading a summary of Ciel nosurge before jumping into Ar nosurge. Ar nosurge is direct sequel to Ciel nosurge, so there will be a few events in Ar nosurge that you'll understand fully only if you've played Ciel nosurge; on that note, this actually happened to me while playing the Japanese version of Ar nosurge, at a couple of instances I was like "wtf, what is going on?" since I've never played Ciel nosurge nor having read the summary at the time.
