I just hope none of them glitch(for both trophies and achievements).I doubt they will be but I would always like to be sure they won't.
Or you could always combat spec.
So that once you get the achievement for Guns you start using EW only until you get the next, then start using Unarmed until you get the next and continue on and grind and explore.
Cake-walk achievements.
This is what I plan on doing .I'll get them along the way.They'll be easy but probably time consuming if you keep waiting for it.
To be honest I'm not playing the game for the achievements I could care less what they are, I think they're just fine. :tops:
I usually get trophies for games for some extra replay value.I'll get them along the way of playing NV as they're pretty straightforward.
