I'm just gonna say this, I don't get STALKER's story. I mean, it takes place is Chernobyl or Pripyat, but... I don't 100%
get it. But I fucking love playing it. Dying in STALKER is your fault most of the the time. It's mostly you do something stupid in thinking that it's like a normal action name. The game is quick in saying this, in the harshest way possible. You're like
"Oh hey, this is gonna be a good action game." then stalker goes
"No it's not. There's more." then probably punches you in the face. It's fun, I enjoy it. I like shooting my own nationality in games. You're a Russian shooting other Russians.
Fallout 4 is basically STALKER in America during the retro-future 50s, its a FPS focusing more on exploration and gunfights with the primary means of upgrading being through use of special items like clothes and bobbleheads (artifacts) with a excellent perk system that will probably be better to what their aiming for. I just hope there will be mods that add back in the more RPGy elements.
Plus there's, like, civilization building stuff.
