Not posting in the thread since I don't want to give the wrong impression to people. I'm not exactly comfortable with talking about a first party game, but I'll be sure to spoil MGSV for you in a few months.
Anyway, please keep to yourself.
There are no spoilers, or any specific details that could potentially ruin anything here for you.
I'll explain to you my taste in games, so you have an idea of whether my opinion is really worthwhile to you or not. I don't like open world games. My preference in games is something linear and focused for the most part. Partly because I don't have time to spend running around for hours doing side missions, but also because I'm not really a fan of open world game design where everything can sometimes feel disjointed.
A good example being the recent Shadow of Mordor, a game I enjoyed very much thanks to its great combat, but where the story and events are disjointed to the point that it doesn't really feel like I went on much of an adventure by the end. If you've played that, I think you'll understand where I'm coming from.
The Order: 1886 is a third person shooter, heavily cinematic, and as such, most of the time you spend playing this game will be shooting at things. There are moments where you can take a breather, and do a little "exploring", but these tend to be more in the Uncharted vein than anything else. The core of the gameplay is in the shooting.
The important questions:
How does the gunplay feel like?
How is the hit detection?
How is the control aspect, and skill aspect?
First I want to bring to light two games that I can draw a comparison to here. One is Vanquish, purely because as great as the mechanics in this game are, the enemy feedback when getting hit is very lacking. The other is Uncharted 3, one of my favourite games, where I felt there was a clear problem when shooting at enemies (in contrast to UC2 which felt very good). Even if I felt I was hitting them, they didn't seem to react well, or it felt like something was off in my bullets hitting them. This created some frustrating moments from what I remember. This was an aiming issue.
I pointed out those two things specifically to give you a comparison point for what I'm trying to convey next. The Order: 1886 doesn't suffer from either of these issues. When you're fighting the grunts of the game, there's good feedback when you're landing hits in terms of body reactions, and it doesn't feel like there is an issue with aiming correctly and missing either. This helps with the skill aspect, because as you're improving and mixing up your tactics, you'll noticeably feel the affect. I was rusty when I first started playing it (my last TPS was The Last of Us almost two years ago), but I adjusted quick enough. The gunplay is satisfying to me, and it's brutal. A lot of blood and gore. There are plenty of moments, with different weapons and situations, where you get some really violent encounters.
Most of the time in the game is spent fighting, but RAD did a good job of pacing the campaign well. I think this is very important, and it's going to be one of the significant aspects as to whether you really like this game or not. How well that clicks for you. There is a good mix of raising the tension, stealth moments, chaos, and some more varied encounters thanks to the unnatural enemies, and situations you're placed in. It's a story focused game, and there are some nice creepy moments that really add to the vibe of the setting. The story itself is somewhat simple, and I think is executed well considering the campaign execution.
The game is the most gorgeous one on the PS4. Ignoring Drive Club here since that's a bit of a different case, but I'm sure some will make the argument for that too.
In terms of my overall opinion, and this is my opinion alone, and I say this not as one of my half a dozen personas that I use on GAF but me, it's my favourite current gen game.
To give you some further perspective on that:
The Order: 1886 - 9/10
Grand Theft Auto 5 - 9/10
Super Mario 3D World - 9/10 (co-op only)
Infamous: Second Son - 8/10
Driveclub - 8/10
Shadow of Mordor - 8/10
Super Smash Bros. for Wii U - 8/10
Assassin's Creed: Black Flag - 7/10
D4: Dark Dreams Don't Die - 7/10
Dead Rising 3 - 7/10
Mario Kart 8 - 7/10
Knack - 6/10 (co-op only)
Killzone: Shadow Fall - 6/10 (campaign only)
That's what I've played on current gen, and how I rank them in order of enjoyment.
I'm a big fan of TPS (one of my top two genres of choice), especially thanks to Uncharted which is one of my favourite franchises, so naturally I believe you may not like this game as much as I do. Taste is a subjective thing, and I respect that. As long the mechanics aren't broken, which in this case they aren't, it comes down to how well the campaign pacing, the art direction, the story, the characters, as well the gameplay mesh, and whether they're satisfying and resonant with you. I think a 9/10 for me probably means an 8/10 for most others unless you have a similar taste to me.
I feel that the game will end up with an 80s metascore even if some critics are harsh on it (since this seems to be very important to GAF), and most will agree it's a solid TPS game. I, personally, think RAD have done a great job.
Take from this what you will, whether it's helpful or not.
