Are there any? Is that even allowed? Do developers use tricks like changing the color of the blood to make them more kid friendly?

The reason I ask is because I was thinking up this game concept, but the target rating is E. The thing is, I want it to be the type of game that truely can appeal to both children and adults alike, much like Ocarina of Time and Majora's Mask do, and I want to see what I can get away with.

Now I'm not talking about obcene amounts of blood either. Just little drops or subtle death sequences. Look at Hyper Light Drifter for reference.

The same question concerns "gore." I quote that, because I don't mean like Gears of War gore. Again, look at Hyper Light Drifter for what I mean, but basically when you slice a monster, a limb may come off, but because of the artstyle (Think Journey-A Link Between Worlds-Hyper Light Drifter-No Man's Sky-Metroid Prime Trilogy) the cuts are more cartoony, and less "gash-y."

Any examples of E games with minor blood or gore? I'm okay with leaving them out because they can honestly turn into gore candy, but I want to know if there are ways to leave them in without forfeting an E rating.

Unless you factor in colorful "blood" from aliens or disney characters, there really isn't much.

Plants vs Zombies is extremely gory and rated E. It even has beheadings!

I can't think of any examples off the top of my head. Is the minor blood and gore essential to the gameplay, or just a visual effect to make it appeal to adults more?

Ocarina of time is rated E and that game is fucking scary. Ganadorf spews blood at the end but in the US and EU version they made it green instead.
However this game is from the 90s so...

What about Jak and Daxter? (particulary the Collection)

And I don't know really as I only played the Wii game, but doesn't Rune Factory 4 has blood when slaying monsters? It also deals with curious themes, like romancing people on the village!

You don't need to put blood in it to make it appeal to kids and adults.

Only the first game was rated E. The second and third were rated T, as was Combat Racing. Daxter on PSP was E10+, as was Lost Frontier.

Version 1.0 has red blood in the U.S and EU. Version 1.0 also has the muslim chant in the Fire Temple.
