Summary: Sonic Rivals was one of the first games I got for my PSP. It's fun when you start, and it's pretty cool collecting cards, but then it gets really boring and repetitive. I always try to collect new cards, but I always get the same cards. And the roster is also sort of boring.
Summary: i'm a huge sonic fan so i'll buy any game i can, provided i have the console to play it. when i saw one copy of sonic rivals at kmart, i had to buy it. my favorite thing about sonic games was running fast. not looking for emeralds, or shooting targets, but running.
Summary: Sonic Rivals pits Sonic the Hedgehog against some of his buddies that appeared late in the series. Knuckles, Silver, Black etc. I think about the time Sonic started having buddies was when the franchise became less fun.
Summary: On paper Sonic Rivals should be THE perfect game. It features Sonic the Hedgehog, the fastest thing alive. It's a racing game. You race on foot through different levels to reach the finish line, hopefully before your opponent does. And it's an arcade styled game.
