In F3 you take the role of the vault dweller and play through a story whilst leveling up and getting new and better equipment
So I guess that makes GTA:San Andreas an RPG? You play the
role of a gangsta home boy, you have
stats, and you have equipment that gets
better through the course of the game?*
Also I lol'd at your "if I have to read lots of text I get bored easily" line. That's exactly why games are all becoming shooters and other types of fast-paced brain-dead tripe with little/no storytelling.
*FO3 doesn't offer enough in the way of character development & diversification to be called an RPG. There is only one way for your character to progress in the game: shooting things with guns. And even then you can't really explore the difference between a sniper character and a gunner, because the game doesn't force you to specialise either way. Any character can pick up and use just about any gun, with good success. Some guy also proved that your stats are largely inconsequential in the game. You can have no gun skills at all and low perception and still be fine in combat.
Also the stats for talking have no bearing on any conversation, bar adding a couple of really inane lines like "oh, you're a scientist!" if you pass your knowledge check when talking to a scientist
The rest of the skills - non combat talents - have zero impact on the game at all, beyond being able to open the odd locker room for a bit of extra ammo.
I'm sorry, but to call FO3 an RPG is insulting even to bad RPGs.
