Get to the point, Thor?
Easy => If your intention is to discuss favourite games in a pares inter pares atmosphere - then I advise refraining from killer phrases implying generalism, absolutism, arrogance, inflexibility.

If your intention is to force your opinion unto others => then keep the way you phrase, but state this intention clearly then, maybe in this manner:
"I, Thor the Allmighty- Lord of War, thunder and lightning - state this... (put in what you think) as a postulate for once and for all - carved in stone, the one and true statement. Any one disagrees? No, I don't think so - good, no need to throw my hammer then."

Short enough? <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />

And my personal point about games is this => There is no official best game ever, period - only personal preferences.
