These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Game Breaker: Nakoruru, who became the most dominant character thanks to the ratio system. At the time, she was only the second character in any Capcom made fighting game to be banned from tournaments.
Porting Disaster: The PS1 version; nearly all of the presentation of the original was stripped down (since the PS1 doesn't have the tech power for the high end graphics), losing stage intros and other animations. Had Loads and Loads of Loading heaped onto as well. It still plays pretty well, but feels so bland as a result.
Scrappy Mechanic: The Ratio system, wherein each character was assigned a specific "Ratio" denoting that character's overall strength and durability on a 1-4 scale. Teams of up to four characters can be assembled, but their total ratio value can't exceed 4. CvS2, which also balanced out and expanded upon the Grooves from CvS1, would do away with this and implement a "free" ratio system, allowing players to create teams of up to three characters and give each character ratios (up to 4 in total) as desired, making the system less limited and cumbersome. The option for basic 1-on-1 and 3-on-3 matches without any ratios involved were also included.
