I will rate it, as a Samurai Spirits fanatic and as a Fighting game player. Let's begin
Gameplay: Yeah, a worst point of 3D Fighting games is the lose of that gameplay everyone likes. Samurai Shodown is a 2D game, changing it to 3D was a great challenge that they didn't win. Even with this problem, the gameplay is Medium.
Graphics: The PSone graphics were not a wonder, but I think they would be able, at least, shape the heads and the body of the chars a little bit more, cause they resemble a Box. =P
Sound: The Sound is COOL ! The narrator screamin' in japanese is awesome, the in-game talks are great too. The Sound is a positive point.
Value: I usually don't comment on "Value",since its personal but with SSWR I'll do exception. For Samurai Shodown fans, like me, the value is 10, of course. The possiblity of see Haomaru as a Forty-Aged man is unique. The other char are great too. Sakaki Jushiro with the Gun/Sword weapon and Kanakura Haito are people that MUST appear in another SS Games !!!
