Not difficulty at all, its the rp. Every game they remove more and more and make the characters you can make less diverse.
As well as story and background, i spent hundreds of hours in morrowind and fallout 3 cause there was so much in them, now they are pushing them out without adding more depth.
Ive always been someone who always played on hardest difficulty to be fair.
Take it from a computer science student that is programming his own game CRPG from scratch right now. It's a LOT harder than you, and anyone else, could possibly think of. I've had a chance to speak with the programmers of Baulders Gate and a brief chance to talk to Laurian Studios.
Baulders Gate had a lot of responces the player could choose from, but very few of them actually effected the story differently. Other than changing your character class, there's pretty much very little replay value in the game.
Laurian Studio's did make it where it accounted for every possibility that could happen in the game. You could kill everyone in the game and still beat it just fine. Even without talking to them. However, they nearly went bankrupt before the game was complete. This also put a LOT of stress on the writers for a game that was only about 40hrs in runtime length for a single session.
For my game, choices do matter as it's premises is the journey, and not the end it effects the end of the game. It is a flipping nightmare to try and account for everything, so it needs to be more streamlined. Or Black and White.
Yeah, you were limited to just three to four options. However, those options greatly expand as your companions will actually add their own unique input to the situation, and the characters you were speaking to may even interact with them. So it's not a total loss.
As for depth. It's all there. Each character is unique. More unique then what was given to you than in any bethesda game. The enviorments are even more detailed, and each building and room tends to have it's own story. If not, everything is carefully and skillfully placed. Borrow the game and take a look around. You'll be surprised at what you find.
IF you do get the game, I recomend that if you plan on playing survival, start on survival. If you go into it midway through, it's slightly easy. But if you start the game with it, then it's rewarding. You can get killed real quickly by rad roaches, and getting shot once will nearly kill you. They made damage realistic. So not only do you take more damage, you output more damage as well. If your enemy's head is not covered with a helmet, you are basically almost always getting a insta kill (Wear a helmet, you'll be surprised how many shots that land on you are actually headshots). Same to you though... take a blow to the head and it's death. And the more enemies you kill, the harder you hit. You can only save by sleeping, and you can no longer fast travel.
Oh, and robots are basically Deus Ex Machina. They eat a heap of bullets for breakfast.
