Many have called Ready 2 Rumble Boxing the Dreamcast's first killer app and, for the most part, I'm inclined to agree. For Dreamcast owners, since the present library is slim, picking up Ready 2 Rumble Boxing is next to a no-brainer.
For serious boxing sim-heads, Ready 2 Rumble Boxing isn't the Second Coming, but then again, neither is the license-dependent Knockout Kings 2000. Those looking for something with a lot of spunk, tons of laughs, and an overall rousing good time, Ready 2 Rumble Boxing delivers.
PlayStation and Nintendo 64 owners should be getting respective versions almost any day now, but it's safe to say the Dreamcast one, with the generation gap in hardware, will be superior in almost every way.
