Summit: Or you can be stealth, badass power armor sniping rifleman with exeptional melee skills, master trader, silver-toungue devil, scientific genius (at the age of 19), all rolled in one character, without any fuss. Great role-playing
That is where F3 failed. Just like oblivion did.
Well you totally missed the point. Yes a power gamer would do that. Someone who is interested in role playing would place limitations on themselves and make choices about character progression that fall with in the chosen concept of their character. Also just cause your character can wear power armor doesn't mean you have to. Role playing is about making choices. Fallout 3, Oblivion and Morrowind all give the player many choices on how to play the game and how to develop their character.
If you want to do what you suggest you can, but it won't feel as much like role playing as it would if you were to say decide not to use the power armor and stick to sniper rifles for weapons, using stealth to get into position ect.
