Ex. of the "I/O shield blood sacrifice"

Man: I was about to throw the whole tower against the wall! I felt like such an idiot. The IO shield is evil and requires a blood sacrifice!

Friend: It really is. I did a case transplant on Friday and it took blood even just for being moved from one case to another.

Melty Blood 

A fighting game made for Japanese audiences, currently this is also one of it's most popular ones. Based on the eroge/hentai game (depending on the version), Tsukihime , this fighter made by French Bread (and Type-Moon itself for ReAct and after) has a fighting system similar to a simiplified Guilty Gear but with a tighter gap for air combos and the shield being a parry/super counter.

While the main story is that Shiki Tohno, the lead role of Tsukihime and original sayer of "a cat is fine too" , must help the heroine Sion from turning into a vampire, this is unknown to most who haven't played it outside of the arcade since the story is replaced by a typical "powerful being gets bored" follow-up.

"This is Melty Blood, one of the examples that anime/doujin games do not have to suck."

Spartacus: Blood, Sand, and Cock

A drinking game in which any time a spoken or visual reference to blood, sand, or cock appears, all players take a drink.

References can be changed or added at any time for the slower and more dialogue-heavy portions of the episode, as long as the drinking continues. For example, references to tits, amputees, or any time someone says a word that ends in -us can all be added to the further the liquor consumption. Synonyms for any of the three words -- such as "dirt" or "shaft" -- can also be used as references.

Spartacus: Blood, Sand, and Cock example:

Lucretia: "Oh, Jupiter's Cock!"
Me: Cock! She said cock! Everyone take a drink!
