Taking a break from Animal Crossing: City Folk to play Sonic Adventure 2 Battle

I've done enough scavenging and paying off my mortgage for awhile. When I bought a Sega Dreamcast many moons ago, I bought Sonic Adventure 2. It became one of my favorite games. After having sold the Dreamcast, I had a chance again to play the Sonic games, as it was ported to the Nintendo GameCube. The only major difference is that it has a two-player mode, having people compete each other for the fastest time completing a level. Also, it is not so difficult that I cannot complete it.
