Full Main Quest spoiler alert!
Dear Bethesda,
Seriously, it's getting absolutely ridiculous. It's kinda hard to role-play any character other than being either psychopath or mercenary because every quests or every exploration requires killing and killing and more killing. It's getting really boring when every location is always filled with bunch of baddies, some notes/computers and that's it.
Few examples, that Robot Racetrack? Ya know that cool place that has announcer and bunch of people gambling on robots to see which robot is the fastest. Hell, there's even a note on one of the dead mailman where it says that a guy is gonna bring his robot to race too. Simple, cool backstory but... unfortunately Bethesda thought that they didn't have enough violent areas so they turn it into a another violent area to kill and loot. Instead of it being harsh but friendly enough to allow players to gamble. They could even give player an option to cheat by hacking one of those terminals to slow down other robots or something.
Combat Zone, that place where Raiders are betting who's the best fighter in the arena? Yea. Great job, Bethesda. Once again you refused to make Arena(Bethesda planned to make Arena in Skyrim at one point but didn't finished it). That place is just filled hostile raiders, loot and a companion you can hire after... killing everyone. Why not make it a place where players would need to pay... 200 caps to enter the Combat Zone where they could interact with bunch of Raiders who aren't hostile. Giving players a chance to talk to Raiders, learn more about them and maybe join the fight in the Arena. Another wasted potential.
Gunners. Really Bethesda? "We need stronger enemies for players to kill... hmm. Talon Company? Nah, it wouldn't make sense. Oh I know! Gunners. They are basically like Talon Company buuuuut! They wear green uniforms.". You guys could've at least given them same AI as Scavenger has on hostility. When you get close to scavengers they usually aim at you and warns you to stay back or they'll shoot. Why not give that same AI to Gunners? Right now it feels like that Gunners are worse than Super Mutants or the Institute itself. They are everywhere! They shoot to kill everyone they see, except few who are related in some Quests. Why not make them less hostile? Perhaps allow players to join them and have awesome battle between them and BoS? Once again, another wasted potential.
Main Quest. It's almost bad as Skyrim's main quest. Every quest requires you to go and kill, kill, kill, talk and then back to kill. I know Kellog has been discussed much but why we have to kill him? Just because he killed our husband/wife? He's a mercenary! They do what they get paid for and they won't stop for anything. I wish there was an option to talk and perhaps get him as temporarily ally until Institute business over and then we could have nice duel with him or something. I mean we can be friends with Benny in New Vegas who basically shot you in the head, but we can't be friends with Kellog?
And final thing that bothered me the most... the thing that made me hate Main Quest so much that I ended up speed running MQ and start new playthrough. Father, or also known as http://www.youtube.com/watch?v=0t0uCWjQ6Og! Once again, it's neat twist Bethesda provided buuuuut.... after few minutes of talking he sends me back to wasteland to capture one guy who is guarded by hundreds of raiders in a dangerous docks. ... ... wat? Why not have lengthy conversation about his goals, ideals and etc. like Caesar/Mr.House do in New Vegas? Allow players to negotiation him, tell him that he's wrong at certain stuff but no. Nothing. All we get is few lines and back to killing.
You see what I'm talking that we can only play as either Psychopath or Mercenary? We got no choice but to ask reward, yes or no. Bethesda thinks that player characters should always be dumb idiot who only cares about kill and loot. This stuff is the most obvious in Brotherhood of Steel. Few NPCs treat player as he/she is a complete idiot, and worst of all! So is our dialog options.
Why have so many violent locations, quests and people? Players usually remember all the funny dialogs, scripted events and etc.
As MrBtongue said in his http://www.youtube.com/watch?v=5ZM2jXyvGOc.
"Slow down the violence, not stop it, slow it down!"
Btw, I love F4 and it's big improvement from F3 and Skyrim.
