10/10. 🤬 it. People who rate it a 5 should never be reviewers as they're seeing it wrong. When grading a game...never....NEVER compare it to other games in the series and then subtract points for removed/planned features but not add points for added features. Look at GT6 on it's own and it's one of a kind. Absolutely phenomenal.
GT6 would probably get slightly better scores if it was Random Driving Game 1, but not by much. It has a great car list, a great track list, and decent physics for a console.
It also has massive inconsistency in assets detail, inconsistent frame rates, bare bones online, and no real distinguishing features over any other racing game apart from the aforementioned massive car and track lists. The career is straight out of Game Design 101, the menus are still designed to show off instead of be functional (3 pages of Miatas...), and basic features like AI and sound would be panned in any racing game in 2014.
It's a basic racing game at it's most basic. It has a couple of things that it does well, which is why I can understand why some people are up in the 9s and 10s. They get into those parts that GT6 does really well, so they love it. But as an overall game, it's pretty rudimentary.
Honestly, I think Gran Turismo gains as many points in reviews simply on the strength of it's name as it loses for comparison to past titles. And really, being compared to your past titles should never be a bad thing. If you're not making the new release better than the old release, why bother even making it?
(The obvious answer being "for the monies", but that's too cynical even for me. I can't believe anyone would intentionally push out a game that's a step back from the previous version JUST for the revenue boost.)
