maybe because reviews are irrelevant these days? espacialy if it is a japanese game to be reviewed by a bunch of western sites

I disagree entirely.

I recognize that some views are tarnished by a commercially-inspired bias, but by and large professional reviews remain a key element of information-gathering for consumers wanting to know if a game is worth their money.

Pre-order bonuses were once a reasonable tool to bring forward revenue and cement an idea of sales. Now when combined with last minute (or even post-launch) review embargoes, they are nothing more than a scam!

Not to mention preorders are supposed to be a sign of trust and  90% of companies out there have done everything they can to destroy any trust and good will they had - western or Japanese - with obscenely priced season passes,  and special ultimate collectors editions, and microtransations, and overrsized preorder bonuses.  The movement ofreview embargoes to day-of or post launch is just the latest and most blatant middle finger to consumers.  

Also, plenty of Japanese games get fair shakes from western reviewers, I would say most do.  It's just that goofs or negative criticism gets blown out of proportion by whining fans.   

Why should they their job is to review the game , now if the game  featured both the Brotherhood and Kingsglaive  as a package you might have a point , otherwise when the next Halo or Elderscrolls comes out are the reviewers  meant to have read all the books associated with those universes.

This is why I feel some games can't be judged based on only a few hours into them.

That might have been valid once but a lot of water has flowed under the bridge since FF was seen as a purely Japanese game , now it's largest audience is in the west and has been for around twenty years, we aren't talking about some niche jrpg only understandable by it's japanese audience and  a hard core Western audience.

There was a time when FF games were those games. Good times.

The games of FF I did not like were mostly due to a boring story with bland characters and a lifeless world. That includes FFVI, FFVII and FFX. To FFX's merit though, the gameplay and amount of content were pretty nice. It was the only FF after FF3 that did not use an ATB system which made it 100% round based combat. The ability system allowed for a lot of creativity, the monster quests were actually hard and there were so many different secrets and side activities. Blitzball was great until you got good players.

But for me gameplay is only second rate in FF. If I'm not interested in the characters or the world, then it failed. That's why FFXV already failed for me.

I'm incredibly hyped! I'm expecting it to get a 76 meta average. Lots of irrelevant talk about development times, gender of main characters, etc. Few arbitrary things to really bring down the score.

They already did that with FFXIII and it got to 83.
