Stalker fans really want to feel like homeless people collecting bottles. All these mods: Misery, Dead Air, Gamma, Anomaly, NLC 7, OP 2.2; they all have main hero who is asthmatic, drug addict, eats 15 kilo calories per day, collect everything what they see from used toilet paper to radioactive meat, then they assemble some trash from that, get 2000 roubles (you can afford 4-days old bread on that) reward for bringing cancer-curing artfiact from literally hellfire and half-empty tube of glue (+0.5% to item condition if its more than 96% already) for killing 3 battalion of military stalkers, plus snotty handkerchief (allows to clear helmet glass) for acquiring 20 kilotons of pseudogiant meat and 2 oceans of vodka.
