While the other SaGa (Mostly RS2 and Minstrel Song) are very interesting, they are also quite different from this one.I'm pretty upset that I've slept on the SaGa series so long but if most of them are in the same realm as Scarlet Grace I plan to invest in all of them.
The only game of the series that is somewhat close to it is Unlimited. The design philosophy of Kawazu has evolved a lot in 20 years.
