The perfect ten?
A score of ten reflects a game that, within the reviewer's estimation, is something you must buy: this is the message we're trying to convey. On a basic level it's almost certainly the best quality game ever seen within the context of its genre, and that's why Eurogamer doesn't dish them out very often. A score of 10 usually applies to less than a trio of games in any given year.
But all 10s are not born equal. For starters, you might consider that a ten in the RPG genre still isn't as appealing as an FPS that we scored an eight, or be mystified how we could score a football management game a nine when we only gave that survival-horror game you loved an eight. The best rule is to simply rate like with like, and use your own personal taste barometer to gauge whether the genre is of interest to you. Even so, if you're new to a particular genre then something scoring a ten is a very safe bet indeed. As a starting point, the message is you can't get a better game of this type.
Let us make absolutely clear that a 10 is not and probably never will be "the perfect game". There's always something criticisable about a game, however small.
A 10 will inspire the reviewer because it gets so many things correct. It will be something truly groundbreaking and aesthetically successful, be consistently enjoyable, get the balance right in difficulty terms, be technically very impressive, and be polished to a shine. It will leave the player in no doubt that they're playing something special right from the word go and will continue to inspire and amaze throughout. As we've said, this doesn't mean it's perfect, and we'll be sure to say where it goes wrong too, but maybe those niggles are just so minor that you can let it off. Look at anything under a microscope for long enough and you'll see the flaws. But would you kick a supermodel out of bed for farting?
