Just a vote for the "name"

Hello guys. Just a little question.

Which of these "names" you would prefer. Which one "sounds good" among the others?

• 1) Gamavatorium - Game + Observatorium
• 2) GameGamon/GamonGame - Just a play on words
• 3) Gamus Mundus - Gamus is a play on words and Mundus is a "world" (Latin)
• 4) Gammunism/GammuniZm - game + communism (humor ofc)
• 5) Gamistratorum - game + magistratorum
• 6) Igrostratorum - the same as 6 but with igra (game on russian)
• 7) Gamus Infinitum - Gamus is a play on words and Infinitum is "without end or limit" (Latin)
• 8) All of these are bad.

Thanks in advance.
