Is there *any* other reason everyone here insists ItR is not Stalker, but Roadside Picnic, besides that one loading tip with awkwardly translated closing words of RP? I'm only at the Infiltration (Intrusion?) mission where you blow up the door, so I don't know if the plot/lore develops in a more Roadside Picnic direction rather than just staying STALKER but with time instead of weird radiation.
