Ignore the advice you saw in this thread, except for the one about trying the DLCs, and enjoy the game however you wanna play it. Romance both options if you want, be a terrible dad if you’re so inclined, etc. Have fun, it’s your first playthrough so enjoy it unspoiled ane cherish it, you will love it and go for a 2nd, 3rd, 4th, 5th and maybe even more runs and you can minmax things later on in these runs.

The only thing I’d say you shouldn’t do is skip the dialogue and cutscenes, and sidequests. This game has a very well-crafted story (which is the main attraction) and that goes also for the sidequests so enjoy them fully.
