PVP.software will be the "developer / publisher" for the "software / video game" known as:
Maze Raiders
Part of the "Maze Raiders and Labyranth Hunters" property.
The official title of the franchise might be "Maze Raiders and Labyrinth Hunters". I believe the title "Maze Raiders" is preferable because it is catchy, fun to say, rhymes, and short. However, Labyrinth Hunters is also catchy, easy to say, and rhymes. The idea of two separate games, known as Maze Raiders and another game known as Labyrinth Hunters, is redundant because the words are synonyms of each other, and because I don't need my two properties to compete against each other. I hope it is known as Maze Raiders, even if the official title is "Maze Raiders and Labyrinth Hunters".
It is common to refer to MMO games and RPG games using abbreviations. The abbreviations don't really work when referring to this title as: MR or MRLH or MR & LH. MR can be a weird abbreviation because male names are referred to as: Mr. Family-Name. I believe just referring to the game as "Maze Raiders" is good enough and the "Labyrinth Hunters" part might only be in the title of the franchise. Or, refer to the official title "Maze Raiders and Labyrinth Hunters" as just "Maze Raiders" would be ideal.
I could also name it Labyranth Hunters. Apparently it is spelled wrong, yet the word "ran / run" is in this version of the title. This spelling would be ideal because it reminds people about physical fitness and because players would be running through a maze of in-game content. The word Labyrinth is not a popular term. So, I could make the spelling of this game: Labyranth. And, as the game becomes common, the proper noun Labyranth would be considered the common spelling for the word labyrinth. I could change the "official spelling" of the word Labyrinth in the dictionary (or the dictionary would show two ways to spell the word) because as the game becomes more popular then the proper noun Labyranth would be considered common spelling for the word labyrinth.
