I certainly didnt mean to imply that a game has to be turn based or isometric to be an RPG. What made F3 less of an RPG than F1 and F2 (in my opinion that is) was the diminished affect that the SPECIAL system had on characters and the ability (with little to no real effort) to make any character a jack or master of all trades.
Now granted one could say that if you dont want to role play a jack/master of all trades just dont put points into a diverse number of skills...but so many skill points are available that one would have to consciously deliberately avoid investing in more than a few skills to avoid that.
In my opinion they didnt really succeed in making many Grey decisions either. The Pitt was more or less a grey decision, but it achieved this largely through forcing you to decide to either kidnap an infant or support slavery, and throughout the rest of the game everything was rather Black/White.
Finally the main story was forced upon you. There are evil decisions to be made true, but they are theatrically evil rather than logically evil. Poisoning all the water is evil sure as is blowing up BOS (this games incarnation of BOS anyway) but there isn't much benefit to the PC to do these things. Unless you are RPing a sociopath who wants to watch it all burn or the saviour of the wastes theres no real path for you to take
Agreed about the Evil paths.
I could be nice and find this thing you want over here in this place, but how about I put a gun to your mother's head and force you to give me the quest reward anyway? Wasn't that much more evil... and easier? There really does need to be a full tree of paths here, because evil is not about murder. It's about getting people hooked on jet, setting up a prostitution ring, sneaking around in other people's business and then blackmailing them for it, beating the [censored] out of important characters and holding them for ransom, and giving children Nuka-cola laced with Psycho...
You know, you gotta enjoy the little things like this.
It adds a whole new depth and replayability to the game. More than (accept quest/decline quest/don't meet all of quest requirements...)
Sure, first time-through... I'm a virtual saint. Second time through, well, I want to be diabolically evil but it just doesn't pay enough. I basically just go around the Capital Wasteland scavving and shooting myself in the foot.
