If Fallout 3 is a spinoff (which I don't see how it is, I mean, the new location and gameplay styles didn't make GTA III-onwards spinoffs) then I doubt we'll see a non-spinoff game for a looooong time.
What is a spin-off? (in your opinion)
Tactics is a spin-off of Fallout, and it has a hell of a lot more in common than FO3. (and like FO3 takes place in a new city, with a new brotherhood
)
My notion of a spin off is to retain elements of one IP and base a new one on it... Like how the tv show Frasier is a spin-off of Cheers. Different city, different format, and a few old friends from before. (Had it been a sequel to Cheers... Frasier would have opened a bar and attracted a new cast of barstool misfits.)
The game play itself between these products is discordant. Fallout 3 is an RPS centered around the "Play by doing" method [IE. you search for traps and find what you can]; Fallout 1 & 2 were character based RPG's [IE. you could have a character that was an expert in traps, and he or she could find ones that you might not ~because they are an expert].
PC development in Fallout was paramount (it affected what was possible in the the game; If the PC can't manage it, it doesn't happen
*). PC development in FO3 is optional (and deliberately so, as a good portion of the expected market are coming straight from, and mostly concerned with, the shooter aspect).
*There has come about a named concept on these forums called, "The Claw Factor"
(named for those Plushie quarter thief vending machines you find in arcades, Walmarts, and laundromats).
The idea is that the "Claw" is like your PC inside "the box" (the game world), and you are limited to your tool's effectiveness in the game, to get things done. Developing your PC in the game is like improving the Claw for accuracy and friction ~making it better suited to achieve your goals. The idea of such a game is to succeed
through your character (without reaching in and grabbing ~as it were); As such, Fallout 3 [being designed with the opposite expectation],
has a lower "claw factor" than Fallout 1.
This is fine (and fun :drool: ~ for a spin off), but its not in keeping with the core series.
