Yup, it happened to me a couple of times, when i don't know a game exist or i don't care about it, until i read some reviews or watch some videos.
It happened to me with BioShock and Red Dead Redemption, to name a few, and now they are some of my favourite games i ever played.
Now if the non-KOF players or casuals see IGN review they might say "i pass".
I agree reviews are not everything, but they help a bit.
