The bloody mess perk is usless, you will see your enemys explode without the perk and it will feel like more if a reward.
Agreed!
I would recomend choosing the fast shot perk. Also I never really found a good use for science in the game.
But here I must disagree... You need a developed science skill for anything technical, and as for Fast Shot ~I never take it, as it removes the option to aim targets shots.
*I would suggest/ point out the Awareness Perk as very informative, though I never pick that one myself.
**I would also suggest using the mouse to inspect EVERYTHING in sight, and not to ignore the Text panel on the lower left.
***Empathy is another strange, but informative perk to at least consider... It color codes the response choices you have with NPC's
****Gambling too is something to consider (though its of limited use late in the game). I once had a level 1 PC that went into a Casino with 5 caps (and tagged Gambling), and he left with 1500. B)
Lastly, I'd recommend advancing all skills that can be advanced with books, all the way up to the Book max (91% IIRC), before seriously investing skill points into them (unless you just have to for a given situation).
