So I love Fallout. I've played the everlasting hell out of New Vegas (I'm replaying it again, actually), and I just beat Fallout 3.
But I also own Fallout 1, 2, and Tactics. But I got just outside the Vault door in Fallout 1 and... Stopped playing. I just couldn't get a feel for it.
So can someone tell me how to get used to it? The style is so jarring from the Elder Scrolls/FPS style I'm used to.

.. Shady Sands will be the first town you encounter and it could be very boring there.. If you know the history behind shady sands from Fallout New Vegas, it may be a little more appealing but I doubt it. Also, it is an RPG. You really have to get in the mindset to get the water chip. I am basically saying, force yourself to care just at the beginning.. You won't have to force youself forever because the story becomes really good.
