No more role-playing or character customization in FO3 than in bfbc2? You must not have played either game if you think that is the case.
- FO3 storyline is non-linear, ie you don't have to go in any particular order and decisions in one part effect what happens in a later part, bfbc2 does not. You play level 1 > 2 > 3 > 4, etc…
- FO3 has moral decisions throughout the game, which impact how the game plays out, bf does not.
- FO3 has an open environment that allows for exploration, bfbc2 does not.
- FO3 allows for you to choose how your character progress with regards to strengths and weaknesses, bf does not. The only thing close to this in bfbc2 is the online class progression, which is strictly linear.
- FO3 allows you to choose what your character looks like, which has become a staple of RPG games. Granted it’s limited, it’s still more than bf does.
Not to be rude, but you really have no concept of what an RPG or FPS is if you think FO3 and BFBC2 are even comparable games. It’s apples to oranges.
Another analogy would be to compare Oblivion to Call of Duty: MW... it just does not work.
