I've been playing this. I like the game and like the scope of it: I always feel like the underworld is endless and I can just keep following tunnels to find something interesting. The oddity system keeps the pressure off me to kill everything, and makes stealing for a living (in xp terms) quite viable.
Last session I was trying to find a secret entrance to some plot point in one town, got lost, barely made it through some scary areas with my life intact, discovered enemies not only use stealth too, but lay serious ambushes (being a horrible cheater I cheat by reloading and throwing a grenade in the area I think they are). I ended up finding a completely different town I hadn't been to, after straying from tunnel to tunnel for a few hours, but in the process I found a good number of oddities, so I am closer to leveling up than I was after doing a bunch of plot related quests.
I like the oddity system, I really like the character system. I am not wild about crafting: I feel like I sank some points into it and still can't make anything decent, and that I need every damn crafting skill in the game to make anything that I want. It also doesn't make any sense: e.g. to make throwing knives at first I needed 20 mechanics to use up the insanely heavy metal plates requires and 25 biology to apply cheap poisons. I raised my mechanics the 20 points (a serious investment) Now I keep finding metal plates that require 40 or 50 mechanics to make the same damn knives. I will need to invest 30 more points into mechanics before I can make my own knives again, or I could just buy the damn things (money is cheap and everywhere) How does this even make any sense?
I also (and here I realize I am being a bit unreasonable), think the weight and trade systems are trying too hard and turn out less than fun. I am always fiddling with my inventory because I have too much loot I cannot sell because the merchants only want to buy the stuff that I want to buy (and never guns, never goddamn guns. Even the weapon merchants will only buy three at a time). As a result I always have 15+ guns in my inventory, and have to keep throwing guns away to make room for other loot.
I also don't understand how you are supposed to play the game without copious rogue skills: lockpick and hacking are both mandatory for many quests and quite a few areas feel purposefully too difficult to deal with without some sneaking around. Things like tunneler murderers will kill me in one round if I don't start the combat on my terms. In early game, security bots and mines caused me a lot of frustration. Basically, reloading is necessary if you aren't built for X threat, but any threat is manageable and the autosaves are plentiful.
As a result my build is turning into pirate-ninja-zombie robot, even though I am trying to keep my main skills (sneak, throwing, mind control, psychokinesis) maximized. The feat system is especially good, since with my current feats I can toss of a pile of psychic damage without using AP and then finish everyone off with my throwing knives, getting ap back everytime I score a kill. Functionally this means I either win in the first round, or have to run away, but I still appreciate that my weird little build is viable for me.
I think next time I will be a pure psychokinetic adept monk with electric gloves and psychic punching. Punch everything for a million damage, use all other skill points to become master thief.
