I'm with RetroAmerica and am in the "good writing comes first" camp. Depth and moral complexity are what make a story worth revisiting, especially when allowing the player to be involved in the decision-making within such a story (e.g., truly an RPG rather than something else). Personally I can't play FPS, so I wouldn't want to see a FPS remake of F1/F2, though such a beast certainly would help expose a lot more people to the great writing from the first two Fallout titles (presuming that the writing translates to the remakes): people who didn't get into the titles originally because they weren't FPS. So honestly, the more I think about the notion of remakes, the better an idea it seems... even though personally, I wouldn't pay for the remakes if they were FPS and would rather see new works with good writing and an RPG focus than anything else.
