Sonic the Fighters/YMMV

Anticlimax Boss: After the grueling battle with Metal Sonic, you're treated to a 15-second fight with Dr. Robotnik in a Powered Armor, who can be almost effortlessly taken down as all he's got is a PPP combo and a throw. If you blow it though, you get the bad ending.
Awesome Music: It wouldn't be a Sonic game if it didn't have some.
Game Breaker: Sonic's spindash move, which gives heavy damage and is fast-hitting.
It's Easy, So It Sucks!: The most common complaint against the game is that it's very easy compared to most fighting games. Some even claim that you can win by holding down one button.
Older Than They Think: This was officially the first game to give Amy her iconic Piko-Piko Hammer. While intended as a gag, it stuck, and became her Weapon of Choice, and she's rarely seen without it. Fans unfamiliar with the game generally assume Sonic Adventure did it first.
Vindicated by History: On its release, it was one of the most critically reviled spin-offs of the franchise due to its unbalanced cast, overly simple gameplay, and due to it being perceived as a poor Follow the Leader attempt to cash-in on the popular fighting game trend at the time. As time has gone by, nostalgia for the game has greatly lessened the initially poor reception, and it is now considered a fun spinoff with unique characters and gameplay. While it's ultimately a pretty shallow button-masher, it's still a lot of fun with friends, and the goofy animations still make it amusing.
