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.
YMMV: Melty Blood
Crazy Awesome: Kohaku. Oh sweet merciful Christ Kohaku. Almost all of the random weird shit that finds its way into Melty Blood, like Mech-Hisui and Neco-Arc Chaos, is directly her fault storywise.
And lets not forget her story in ''Actress Again'', especially her dialogue with Roa.
Kohaku is also such a nerd that she modeled Mech-Hisui's attacks after an Android Ranger from her favorite game, Phantasy Star Online. A consultant from SEGA was actually called in for this during game development.
Ensemble Darkhorse: Kishima Kouma has a bit of a following among fighting game fans who are unfamiliar with or otherwise not fond of the Tsukihime universe due to his more traditional fighting character design, and works as a sort of gateway drug to bringing new players to the game.
The original game, while being a fighting game had a very big emphasis on the novel-like story. Subsequent releases not only removed this story, but also threw every sense of Canon out the window and added stories that don't tie into the original games at all.
Many story-oriented features and easter eggs got removed in order to make the game more balanced. For example, in the original game Red Arcueid had Super Armor at the beginning of each attack, and standing near V. Akiha would slowly reduce one's health (which made perfect sense, as her power was plundering energy via body contact.) as for easter eggs removed one of the more famous ones is in the original game using the shield to block Ciel's forward+weak attack x3 (one were Ciel does 3 sets of boxing style punches) attack with Arcueid will after she stops the 3rd hit of the move will cause Arcueid and Ciel to reenact a silly Cross Counter scene from Kagetsu Tohya this was removed in Re Act.
Excuse Plots got added, in order to make characters, which were according to Word Of God not going to make an appearance, appear anyways.
Despite originally being a PC game, Re-Act was the last game exclusively made for the PC. Both Act Cadenza and Actress Again were first Arcade games, then got ported to the PS2, then again into the arcade and lastly got a PC port based on the PS2 version.
