Not sure that relates to this, but that's ok.  Anyway, we don't use the whole spectrum because that's the concensus we have.  I'm someone who reviews games, and in order for my reviews to be relevant, they have to be comparable to other reviews.

So lets say that the industry at large considers 5 to be a very bad game that should be avoided, which I think is true.  And suppose that in my opinion, 5 is an average game that fans of the genre would enjoy.  So, in reviewing a game, I give it a 5.  In my mind I'm saying "average" but to the readers, I'm saying "bad". 

In other words, I have to use the language that the industry and its consumers have implicitly agreed upon.  If I go my own way, it leads to misunderstandings.

if Sony advertises the game, we'll see sells likely along the lines of the originals.

After dominating the genre last gen Sony has pretty much abandoned platformers with PS3 (aside from Ratchet). I think it's far too late in the gen to revive this genre on PS3.

But I like Sly - I hope it does well. Would love to see Jak return as well. Never understood why Sony departed from what worked so well on PS2 (Jak & Dexter, Sly Cooper, etc) when they launched PS3. Even most 3rd party platformers skipped PS3 (Spryo, Crash, etc.)

just describe your review scale in detail like Gameinformer

your last 2 sentence are right,but

the mario games rated so low were either because of too much recycling in a too short period(nsmb(u)) or because of the dissapointment that paper mario was not what it should be:an Rpg.

but you will nowhere read such overwhelming critics for sly than you will for mario.

just take any 90% review from the latest rayman(nothing to do with sony) and mario.the rayman game is described more in a professionell way by the raters,mario reviews always sound like magic,phantastic,jesus returns etc.And i'm pretty sure the same will happen with the soon released rayman wii U exclusiv.

as result:rayman3ds sales=10000,mario2d 3ds=5mio(that's why i'm pretty sure that 

Unfortunately, you can't count on every reader to look at that.  Readers often have a short attention span.  I love it if readers read the whole review, but I know plenty are going to just skip to the bottom.  The issue is even a bit more complex when you take things like metacritic and gamerankings into account.  Those aggregate sites depend on a concensus.

At any rate, what does it matter either way?  As long as there is a concensus on what a rating means, that's all that really matters to me.  I'd rather be able to easily read and interpret scores than have to reference each site's scale whenever I read one.

Ratchet has always been here throughout PS3.  A little too much recently, in fact.

But I agree with you.  I would have loved to see Ratchet, Jak & Sly continue on PS3 right from launch.  Problem is, Insomniac could manage two franchises on the run at once, but Naughty Dog couldn't (until recently) and Sucker Punch are a pretty small team in general.  And they all wanted to try new things with the new hardware.  

It's promising that Sanzaru have appeared to continue where Sucker Punch left off while staying true to the originals.  Bodes well for outsourcing the IP's in the future, you never know what might happen.  Perhaps Mass Meda or Ready at Dawn or someone will be handed the Jak IP in the future.

And OT: I will be supporting it, when it releases in Europe :)

I will once I finish my back log of games.

Rayman's lower sales have little or nothing to do with its sales.  The fact is that Rayman is a B level franchise at best.  Mario is a franchise that's been around for 25 years and includes some of the best and most innovative games in gaming history.  It's unrealistic to expect Rayman to compete with that.

By the way, NSMB 2 had an average review score of 78% and Rayman Legends was 88%.  I've read a lot of reviews for bothand I really don't recall reading much overwhelming praise for NSMB 2, much less Jesus returns reviews.  Those may be in your head, but if you have any feel free to post them. 

And it's not hard to see why NSMB 2 sold better.  Rayman was absolutely beautiful, but to be quite honest I felt its level design wasn't quite as strong as other contemporary platformers.  The levels just weren't as memorable as some of the best 2-D platformers (like Donkey Kong Country returns or NSMB Wii) and even fall below some of the somewhat lesser 2-D platformers like NSMB 2.  In addition, Rayman was a lot less accessible, and didn't feature a hyper popular protagonist.  If reviews were a main factor, the game would have sold alot better.  Rayman definitely deserved better sales, but honestly I enjoyed NSMB 2 a bit more.

Gonna get the vita version once it's released in the eu.
