Meta is just an average of opinions called reviews, without reviews nobody could know which games are generally considered good or bad before buying them, so they're useful in some way. Sales on the other hand don't mean anything for the quality of the game, hence my sentence. So Meta info > sales info for gamers.
Meta says the average opinion of reviewers in 2009 was that 2 PS3 exclusives were worth 90+ / 100, and zero 360 exclusive full game was worth 90+. Nothing more.
You can still prefer Halo Wars and disagree with reviewers.
