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.
Deader Than Disco: While never hugely popular, Clayfighter was a pretty successful and well respected fighting game franchise during the 16 bit era. After the 63 1/3 debacle, good luck finding anybody who will admit to ever liking the series. And, needless to say, no new games have been produced ever since (although the original did get a Virtual Console re-release).
Ensemble Darkhorse: For all of the problems C2: Judgement Clay had, the general consensus is that Hoppy is the best thing to come out of that game. The creators seem to agree, as he's the only C2 character to return in the next game.
Game Breaker: Taffy and Ickybod Clay in the first game, because the former had long reaching attacks & the latter could teleport.
Also in the first game, The Blob. His signature buzzsaw move(where he'd turn into a saw blade & rocket towards his opponent) used to hit the opponent repeatedly if he or she blocked, dealing more damage then it is supposed to! Nowadays, it just stops when the opponent blocks.
Blob's manic grin when he appears on C2: Judgement Clay's versus screen.
Porting Disaster: The Sega Genesis version, which was picked for Virtual Console release.
Sequelitis: Hit with this pretty hard. C2 suffered from mediocre graphics, (according to the producer) a generally uninteresting, limited cast of Shotoclones and overall dull gameplay. Clayfighter 63 1/3 improved on a lot of those things, but due to Executive Meddling and poor reviews, wound up being the Franchise Killer.
That One Boss: The final boss of the first game, who constantly lobs projectiles at his opponents. These projectiles also happen to be from the other fighters. Add in a sick grab move & you have one tough opponent to beat.
