Ok, take 'genuine' out of the question if you want. My
question relates to the suggestion that there can be an
'objective truth' and it is God's.

Since you cannot define objective truth how can I answer the question?

I can't really define objective truth because I think it is a
fallacy. However, I suppose it would be along the lines of
universal unquestionable verity. A place where the endlessly
shifting signfier (differance) must end; a place in which
reality resides.

I disagree. And the fact that I disagree is enough to negate your argument. My disagreement is an Objective truth, a fact. I have disagreed with your statement. And I also disagree with the belief that everything is a game.
