I've been playing for a few weeks now and I'm thoroughly enjoying it. I am biased, I've been a huge Star Wars fan since early childhood so I'm already pre-disposed to enjoy this, but, it's a great game. I think it's mainly highs but there's a few lows:
Its huge, there's at least three very big planets to explore and they are packed with well-hidden secrets, easter eggs and treasure to sniff out. Sometimes the worlds feel small, because you are on a speeder going very very fast you can cross the map very quickly. The speeder is sometimes too fast, I've crashed and died on a rock too small to notice. Thats not a bug, that's working as intended, but frustrating. I wish the speeder would auto-follow roads.
Combat for the most part, is fairly fluid and fast paced, its not perfect, there's flaws - but Kay isn't really supposed to be an action hero, adrenaline rush is your friend! You're really meant to be stealthy.
Stealth needs one or two tweaks. I'd prefer a ranged stealth take down and I'd like a way to mark targets while in stealth and an improvement on detecting enemies whilst sneaking around. It's frustrating when you're sneaking around and someone you had no-way to detect or notice spots you, and that's the mission finished. Enemies have zero peripheral vision. But they can see past the curvature of the earth directly in front of them. Their pathing can also be frustrating. A technician can be working at a console for ages but only moves when you're sneaking around the room. They've not noticed you; they just happen to be randomly moving. Some of these things could be argued as being more realistic - but it's a computer game so it can feel frustrating - especially when some missions are auto-fail if you're spotted. Save game is disabled in certain areas and missions for some bizarre reason.
I think a lot of things in the game aren't explained or taught to the player (marking enemies with the electro-binoculars, the contract terminal on your ship etc, there's probably more.) there needs to be a much bigger tutorial.
The expert system instead of skills or levelling up is a plus. The reputation system is good but can be a bit grindy - the contracts can be a bit repetitive, standard computer game fair. Nix or BD-1? I can't decide. But there's been a few instances where I've stealthed and/or battled through huge crowds of storm troopers just to realise Nix could have pick-pocketed a security card, at range, from safety.
Theres a few mini-games, the eating mini-game is... bizarre? Can I turn it off? Lock picking is tedious. I tuned that off. Slicing computers is pretty easy - once it's been explained in a YouTube video. There are actual arcade consoles all over where you can play 80's style arcade games, including the swoop racing from KOTOR. But most importantly- Sabacc. I Love it, its surpassed Pazaak and its up there with Gwent. Here's a hint, something it took me a while to realise - CHEAT. You are supposed to cheat. Its part of the game. Gimme more Sabacc.
Overall, yes, there's flaws, but its still a great and enjoyable game.
