Do you need to get them or if you pick none when you level up will you have 3 to pick from or do you lose those starting perk points? Like I wanted to see insteed of taking wild whatever and like the accurecy perk if insteed i can wait to lvl up then get like 3 more master skill points or w/e

Those starting things are traits, not perks. You only have them available as character creation options. Because they're not perks.

Nope. Doing just fine without 'em.

I'm going to pick up WW next playthrough though. Wanted to see the baseline before adding anything weird in.

You don't NEED them.

I'd recommend you choose Wild Wasteland though.
