I wonder how people understand review scores of big websites. I'll give an example:

I think that on IGN - less than 8 means "a bad game", 8.0-9.0 means "a mediocre game" and 9+ means a good game.

Am I right?

What about other websites? GameSpot, etc?

How is it on Metacritic?

Mine is more like, at least on Metacritic

0-5.9 = nope
6-6.9 = caution
7-8 = decent
8.1-8.5 = good
8.6-9.0 = awesome
9.1 + = excellent

From left to right

Unless you're on an Arabic website.

No, the correct way to read numbers in Arabic is still from left to right unlike letters. Believe the man, he speaks the truth.

Headlines thenn go to the score.

Don´t have time to read.

I see most reviewers on the 5-10 scale scoring 5 or less than 5 is rubbish 10 is great.

The correct way is to not read the scores unless you really, really know you have a similar taste with the reviewer.

For me.

4 - 5 = Rather waste money on fireworks.
5 - 7 = Mediocre and generic.
7.5 - 8 = Okay, nothing special.
8.5 - 9 = Pretty Great.
9 - 10 = Must give it a shot

If it's a game I don't care about at all, but there's a huge discount on it -- it needs a Meta of at least 80, or 75 along with few favorable video reviews. (ex. DEeus Ex: Human Revolution)

If it's a game I'm on the edge of buying, it needs at least 70, or 65 if it has an interesting concept. (ex. Alice: Madness Returns)

If it's a game I followed pre-launch and decided to buy it based on information gathered --- I completely disregard reviews, and never read or watch them, whether meta is 95 or 65 I'm buying it (ex. Lollipop Chainsaw, Destiny.....)

Most of my purchases are from the last category, I usually research games a lot, and decide on my purchases months in advance...
