So wait, is it really inadvisable to play Ar Nosurge before Ciel Nosurge? Then what's the point? NIS can't possibly expect more than a fraction of the potential audience to actually seek out a plot summary in preparation for this game, can they?
KT not NIS XD And nope they're not doing much to help either, but as current fans that's why we're spreading word of mouth as it actually further enriches the experience. But at the same time you can't blame them for what they're doing here. As discussed earlier, Ciel is a very niche game that would have been a financial bomb for KT to localize, but Ar on the other hand is something on the more traditional side that could appeal to JRPG fans in the west.
If I had to make a common comparison here, it's like playing the Milla branch first over Jude's branch in Xillia, you're going to be missing out on a lot of details, but you can still enjoy it.
