Wow...you actually like a RPG. Nice.
Yeah, FO3 is a pretty great cross b/t a RPG and a shooter -- as it has both elements very heavily, whereas much either lean on being much deeper on one side than the other.
I do wish the melee combat allowed me in VATS to target body parts, though -- not a big deal, though. They should do that in some FO3 DLC or FO4. Regardless, FO3 is pretty amazing. BethSoft's best work by far.
