Excuse me, what? I would love to continue a discussion, but quite frankly your post is a logic mindfuck, and simply cannot understand it.
Sorry for making myself unclear.
Again, I have not listened to or been told anything by any XCOM Let's Player, as I haven't watched any XCOM LPs (yet). I have never said anything about any individual Let's Player, so I'm not sure where you're getting that from. I'm talking about the general relation between amateur Let's Plays and professional reviews.
As a clarification, I'm saying that in this specific instance, in regards to the new release of XCOM, the game hasn't been out long enough for most players to
really dig into the meaty bits of the gameplay, so we can't expect a majority of experienced players doing LPs.
However,
in general, people who set up Let's Plays will do so after having been familiar with the game for some time, and in a number of cases after having become quite experienced and knowledgeable about it (unless they prefer doing blind LPs). But experience aside, they'll still be playing with different motives and different perspectives than a professional reviewer would, and it's been my experience that the actual gamers will learn a lot more about a particular game than the reviewers would, because the reviewers are specifically given titles to review whether they want to or not, and are paid to write something interesting about it; not to plumb the depths of the gameplay mechanics and actually figure out what all works and what doesn't (something gamers will do of their own accord, because they're independently interested in doing so).
I'm not entirely sure how else to explain my position. If you could detail a little more what exactly it is that I'm not communicating properly, I might be able to find a better way of presenting it.
Kilroy and Alkhemia also brought up the somewhat important point of reviewer bias. Again, since they're getting paid to write these reviews, that money has to come from somewhere. If that money happens to come from a company that wants a favorable review of their product published, then that's what you do. I somehow doubt there are a lot of professional reviewers out there who would rather uphold the lofty moral code involved in writing a few paragraphs on a video game, than earn a paycheck that will actually let them cover the rent this month.
