Pre-ordered this the moment it was available on Steam. It doesn't disappoint and it's well worth the wait.

Pros:
-Really optimized for PC. You can run it 60fps consistently with no problems even if your rig isn't the toppest of the line. Keyboard mapping/binding is possible, and it natively supports different controls
-Stunning visuals, especially at 4k. The game is a wonder to look at.
-Very rich and jam-packed Training mode. Lots of options for you to set whenever you want to practice a new combo or mixup.
-Gallery Mode contains all the past CGI movies in previous Tekkens for your viewing pleasure.
-Fresh additions to the meta such as:
>Rage Arts - these correspond to supers in other games
>Rage Drives - they work similarly to EX moves in other games
>Power Crush - an armored attack that lets you absorb up to 3 hits of any high or mid attack while being vulnerable to low attacks or throws
-The slow-down when two incoming attacks collide upon nearing KO is mad hype. I found myself enjoying each of these epic slow-mos.
-Customization is packed with options for you to personalize and customize not just your character, but even stuff like your health bar, information panels, and so on.
-Fantastic story mode that really takes advantage of the stunning visuals and immersive soundtrack.
-Arcade Mode and Treasure Battle are really fun and engaging offline modes for people who like to play offline Single Player.
-In the settings, there's an option for "Tournament Mode". This is a really big help for tournament organizers as this reworks the Offline VS Battle into a more tournament-friendly configuration with stuff like disabling pausing mid-battle via the start button or even controllers being disconnected. Every fighting game that doesn't already have this should follow suit.
-The addition of Akuma and Eliza allows people coming from 2D fighting games such as Street Fighter to get into the action while easing themselves into Tekken-style of play since Akuma and Eliza function like 2D characters with sidestepping. They even have a super meter and jump attacks.

Cons, there aren't much but here's some of them below:
-No proper tutorial. Some newcomers might find this a turn off, but to compensate you can just head straight into Practice/Training mode and look at the sample combos near the bottom of the command list of your character. To be fair though, this isn't a real substitute for a proper tutorial.
-No crossplay. The dev team has stated their reasons for this, but it's definitely a con.
-This port doesn't have Tekken Jukebox, a mode on the PS4 version where you can listen and use tracks from all the previous Tekkens(Tekken 1 to Tekken Revolution) except for Tekken 3D Prime.

Overall: 9/10.
T7 is by no means perfect, but it's getting there. I recommend getting this game for all fighting game afficionados out there on Steam, even those who don't play 3D fighting games, because Tekken is that awesome.

Eh, needs some more immediate content tbh.

EDIT(06/22/16):
The upcoming Cinematic Story Mode looks promising. It's a treat that we get to play early as the remaining DLC characters.
