Like the quest when you are transferred to the local prison camp (prison on prison island, lol) and you have to sneak around and do everything without your items and powers?
Or like the quest where you help 2 thieves rob a train?
Or a quest that you stumble upon while exploring - to save a strange man from being held captive by some weird monks?
Or the whole side chain-quest starting with discovering that you're being hunted by someone?
About fast travel - I actually like it. There are 4 or 5 "train routes" on the island, so there are as many terminals to hack. Doing so unlocks the fast travel on that specific route (that's why you probably couldn't fast travel as you say - it was a different route). Getting to those terminals requires flawless stealth. Some might say it's "tedious" or something. I like the challenge. It took me around 20 minutes to just do one enemy camp (these terminals are surrounded by at least 20-30 enemies so combat isn't an option) but it was satisfying.
I also like the stealth itself. Enemies often have different patrol patterns, you can fast-forward time, and of course there is a parkour system.
I didn't even encounter a couple of those quests, but yeah, the ones I did find were all dull fetch quests. None of them were memorable, even the one with two thieves.
When you unlock a fast travel point on the map, it turns blue. Today, none of the fast travel points were blue. They were all white, which is the color they are when you discover but cannot access them. Checking multiple fast travel points throughout the map revealed that none of them were unlocked, despite my then going and unlocking some points at a terminal. None of them, including ones that were nearby, turned blue. All remained locked. It's definitely a bug.
Kinda like the bug where I was doing parkour, just climbing up a cliff, and died for no reason. Or the bug where I was climbing down some rocks and got stuck in a t-pose. Or the bug where stabbing an enemy gave him 100% health. Or the bug where loading on a save sometimes sees you stuck with the status effect that killed you, or spawns a ton of enemies right next to you even though they weren't there when you saved, or spawns you mid-way through a fight with a boss but he's at full health even though the arena's transformed and toxic... you get the idea, right?
How deep are the skill tree and loot systems in this game?
I got a 39 dmg sword at the start of the game and it was the best weapon I had, other than a blue gun (which didn't do nearly as much damage despite being 60 damage), until one of the bosses near the end of the game. Most loot seems to be like... within a weird 5-point range of each other? Like, there's no power growth or anything. I killed a thug in the first city, and his gear had better stats than most stuff. Like, I almost never needed to change gear, ever. I only changed gear 'cause it looked cool, mostly. Combat never seemed to change based on my gear. There isn't a lot of it, what there is isn't really... like... that statistically different. It's really bizarre. There's no leveling, everything's kinda flat, and the stats just don't have a lot of range, so there's rarely a reason to actually change gear. I'd hoped maybe putting on enemy gear would give me a disguise, but it didn't appear to.
None of the ranged weapons felt good to use; you'd think a 60 damage gun would be way better than a 39 damage dual polymer sword, but no, no, the sword will ruin anyone you use it on, the gun hit like a feather duster.
As for the skill tree, the powers aren't really exciting (time slow, teleport, that kind of thing). There's a ton of flexibility, no need to commit to anything. To level, you find stuff called 'nectar' in the world (some is hard to get, some is just sitting next to a log in the swamp), and you use it to buy powers and upgrades. I had a lot more fun with Divinity: Original Sin 2 or even most Diablo ripoffs I've played. The game's only awesome element, imo, is the climbing, which is great except for when it bugs out. I was trying to steal a helmet for one of the main path quests, and my dude got stuck on a ledge, shaking up and down repeatedly before suddenly falling to his death.
I thought this was gonna be amazing. I was real bummed out.
