FFWA is a really fun game, the reason it isn't my favorite hyper game, is because of it's lack of chain combos. Buriki One is great because it's pretty much the only game of its kind behind Karate Champ.
Samurai Spirits 2 IMO is a damn work of art, and the best hyper game hands down. It's also my 2nd favorite Samurai Spirits game of all time behind Samurai 4. If you loved Samurai 4, you'll love Samurai Spirits 2 on the hyper, since it's pretty much Samurai 5 in regards to the MVS series's timeline and characters, since the real Samurai 5 on the MVS (If it ever comes out) is supposed to be like Street Fighter 3, have all new characters except Haohmaru, Genjuro and I think Hanzo or maybe Galford.
