If you think $90 is too much for the real MVS, then yes, go buy it. However, at the last fighting game tournament I went to, I brought my MVS and Supergun. I told everyone "once you play the real Garou, you'll throw away that Dreamcast piece of shit." Well, they didn't throw there copies away but, they definitely agreed with me.
Why buy the real Garou?
-No loading times at all
-Voice tracks come up right on time
-No lag
-No SHITTY, remixed, crappy music
You'll just have to weigh your choices. However, if you get the DC one, I almost guarantee that you'll be wanting something more...
