Yeah, I agree that the game is way, WAY too easy on hard.
When I started out and finally got out off the enclosed start into the more open area, I immediately took one look at the green waypoint in the distance and then ran in the polar opposite direction to explore.
I came upon a shuttle crash and it had three primals, like space gorillas, pretty much. I was packing 10 “medkits”, a pistol with 105 bullets and after defeating my foes, I was now standing there with 4 medkits, a damaged pistol and 10 bullets. I notice something red on my compass and looking over there, another group of three gorillas are sleeping on the ground. Like the brave hero I am, I sneak right up to the nearest gorilla and quickly backstab and finish him off with another few strikes and then run away, very bravely! They give up chase after a while and go back to sleep. Another gorilla meets the same fate and finally only one gorilla left, the big scary one (if you want to imagine a mother gorilla with her few year old half adult kids, know that that thought had struck me too). A backstab and a few frantic swings followed by a short run to gain some distance ensues, carefully trading blows and blocking, healing and running, and then finally the last 10 bullets end the fight.
I am now standing there, two real fights into the game, not a bullet to my name, 1 medkit left and I have not found another medkit from scrounging a few boxes, so I am under the impression that they are rare. This is what I thought the game would be like, combatwise.
Two hours later and I am sitting back, sniping marauders with a rifle that kills in one hit, packing hundreds of each kind of ammo and with 20-30 medkits.
Now at lvl 30, I am nearing 4k ammo of each kind of ammo and I got 105 medkits (I sold 90, because they have a weight, unlike ammo). Only if you use machine guns will you run any risk of running out of ammo, but there’s both light ammo and heavy ammo machineguns, so just alternate, really.
Now, I have died even late game, you can’t just stand there and soak damage, but resources are never scarce.
I feel like tinkering is like blacksmithing and enchanting in Skyrim, they just make your weapons and armor so much better, it unbalance the combat. If you skip using them, you get a more fair fight, but it also feels like you’re limiting yourself, like tying a hand on your back.
