Just had my very first newsletter telling me to pre-order Fallout 4. Seriously... I mean... c'mon...
I am pretty stupid when it comes to pre-ordering and stubborn at that too but... well...
And about the graphics, I agree with Xant. Graphics isn't everything but a big part nonetheless. One of the reasons I just could not enjoy New Vegas. It just looked awful although I whole-heartedly enjoyed Fallout 3. I simply couldn't endure the exact same look in New Vegas. There were other things I didn't like but crappy graphics played a role...
PS: Please don't start a discussion if 3 was better than New Vegas or vice versa. More a question of taste and belief than factual arguments, no point, we've been there.
