In this case it isn't my definition of what is a role playing game. Saying that a game that fails at every role playing element other than exploration is a good role playing game is like saying Halo is a role playing game because you play the role of Master Chief. You are free to say you had fun playing Fallout 3, but saying Fallout 3 is a good role playing game when character stats where mostly useless, combat was almost completely independant of character build, and writing, and thus interaction, was awful is a bit of a stretch, don't ya thinky think?
Examplity Example: My test character in Fallout 3 was something like Strenght 2, Percepcion 4, Endurance 2, Charisma 10, Intelligence 8, Agility 2, Luck 10 or some thingie like that. Tagged First Aid, and other two useless thingies. Took that feat that allows you to be a bitch to males, yes? Really, a totally awful character build. Then i bought a laser pistol, went to a raider base, and wiped every single living thingie in there with that character, no loads, no saves, no troubles. Role playing game, you said? Reaaaaaally? When your character is totally unimportant?
Other than that, have fun walking around the wasteland and listening to, like, three dog. I don't care, nya.
