You haven't played a lot of RPGs then, even those you mentioned above it seems?
You gotta be kidding me. DoS has a few binary choices and some flavor text, that's fucking all. Nothing really impacts the game world, and every quest works in its own little vacuum. Compare that to NWN 2 (vanilla, just because). That's an example of a game where your choices matter. Your race matters, your background matters, your class matters, your alingment matters, your plot choices matter and your build matters in pretty much every part of the game. From combat to conversations (shitload of skill checks) to NPC reactions. If you're a paladin, you'll have paladin exclusive choices, if you're a drow, you can talk to/befriend a spider easily, and people will react to your race with an appropriate comment etc. There's a ton of reactivity and roleplaying choices.
In Fallout 2 you can fucking outplay 4 crime families, join or destroy the slavers (with each choice having it's own pros and cons), marry a woman and turn her into a prostitute (
) etc.
That's roreplaying you know.
And in Divinity... Evelyn asks you to choose which of her patients to cure, just because the devs felt like forcing the player into a "tough moral choice". How ridiculous was the whole situation.
"Hey, i'm the doctor's assistant! I have this healing stone, but i can't decide which of my patients i'm going to save. So why won't you - the random stranger i've never met - choose who's going to live and who's going to die? Because i don't want to, tee-hee!" And if you'll walk out the door, they''ll both die, and i'll blame it on YOU!"...
Really? Fucking seriously?
That just proves this game is an excellent proof of well executed craftmanship. Nothing more, nothing less. But just like i said, i'm not impressed by its story, dialogues and roleplaying aspects. I bet Wasteland 2 has better and more meaningful C&C, even if, as a whole, i consider it an enormous disappointment.
