Marbozir is a Polish YouTube gamer known for playing strategy and board games, but will sometimes play RPG or survival based games. He considers his commentary style to be a combination of an "analytical approach with a bit of sarcasm and dry humor."
He is most known for his playthroughs of Civilization V on deity, the game's highest difficulty. He has played with many different civs, showing his knowledge of how the AI functions. He also plays through XCOM: Enemy Unknown with the Long War mod installed to add further difficulty, although this has been halted due to the release of XCOM 2.
