if this is cash costume, then they're incredibly disappointing, at least to me. The changes are very minor.
Especially the RK costume. Giving us the old RK costume would have been so much better (and will generate much more money too) than simply adding a red sash on the chest.
To me at least, the old RK costume will always be the true and real RK costume, since it actually has rune stones embedded on the armor.
