My experience with RPGs stems from D1 and 2, TQ/Immortal Throne, Deus Ex, TES, and other games with a similar nature. For me, they achieved what I find and value in an RPG. Fo3/FNV both achieved that same end result and I was more than satisfied by it. I admittedly don't RP, but it doesn't impact my ability to enjoy an RPG because in the end I'm assuming a role and following or guiding the character in their journey.
I won't subscribe to your belief that the Fo3 protag's actions are dust in the wind. Decisions can be made that impact the game world - certainly not on the scale that Fo1/2 offered, but they are still there.
It's still Fallout in name and spirit. The only thing that has changed is how the developers allow players to experience the universe.
* With that said, I don't intend to continue this discussion with you so I will bow out. I respect your opinion but I simply can't agree with it. We've essentially come full circle, and I go back to my original point: don't support a developer where the cons in their game outweigh your pros.
Good night.
