Can't say I've used it before, but if I'm thinking more along the lines of food preparation. The way it's served, how it's made out to be, the descriptive language and eventually what it looks like. In gaming, I think it would mean how well the plate was handed to you - was it thrown onto your lap, or was it gracefully placed onto your table mat? How well did it open up, and how did the overall gameplay look? I think that's what they mean anyway. One example of this might be,
"Well yes, the game was very good but it wasn't presented that way." By this I mean, the elements of gameplay were scattered about and you had to pick them out, whereas a well-presented game would let you see it immediately and embrace it.
At a convention, it would probably mean something like the host going, "And now ladies and gentlemen, I ask for your silence and your attention. We're about to bring you the greatest show of all time, the "piece le resistance", IT'S (something)!".
Hope this helps, and please correct me if I'm wrong.
