You should absolutely beat the first game before the second, if you can stomach it. My advice to you is don't make the same mistake i did in my first run: do NOT try to get every settlement to 5 stars as you go on. Just fucking plow through the story until you get across the first major break in the game, you then get stuff that really helps your mobility and you can go back when its all over to max people out if you really feel like it.
I dropped the first game about 70% of the way through on launch because i burned myself out trying to do everything. It wasn't until last year that i started over and beat it all in one shot, and it was worth it
