from first to third, what do you feel has the most importance?
speech, barter, survival.
leave your reasoning!
also, if you're playing on a high difficulty leave that in the comment. don't bother posting the difficulty if you're on normal or lower, we'll just assume.
1st. survival - boosts hp gained from food, self explanatory. very handy on hardcoe/very hard, and some of the campfire recipes are useful.
2nd.barter - i usually put just enough and then some for speech checks. very helpful if you're trying to get implants.
3rd. speech - i honestly prefer doing all of the quests. usually just enough for major speech checks.
I agree it does have to do with he character you are creating, but survival is actually a waste of points, even on hardcoe. Food and water are abundant. The real goal is to just keep from getting your body crippled. Simple eating, drinking, stim packs and sleep with fix your problems just fine. Survival is a nice flavor stat, but it isn't that useful at all. If you like to make stuff, that's cool, but it's impact on the game has it as one of the least useful skills, if not the most, in the game. Food is also cheap and light weight to just buy and carry.
Barter isn't bad, but it is easily the #2 on your list here. It's nice to increase your reward on quests and get better prices when, well, bartering.
Speech is number one. you don't need to take it, but it has the biggest impact on game play. It is an alternative to combat in many situations. You aren't skipping parts of the quest, you are solving them with words instead of bullets. there is an epic moment with the legion, for example, where you can fight or speech challenge your way though it, but you are going to need 100 speech to finish it with out resorting to violence. If anything, this is a staple of fallout and RPGs. It's the ROLE PLAYING part of the game. Are we playing an RPG or Halo? Most of the game asks for exactly 50 speech to get by. there are certain situations where having 75-100 speech gives you that alternate path to completing objectives. The fact that it directly relates to main and side quests as an option, this is why speech has the largest impact of your three skills listed. Survival can't say that and barter can only do this a small amount.
This game is all about having one or two major combat skills maxed out along with speech and/or science. there are tons of science checks in this game, and many of them are 75-80. You can use your major combat skill to, well, survive/win combat and use your speech and science skills to complete quests in a manner that doesn't involve more "gun play."
Personally I am going with a charisma/speech based character over an intelligence/science character on my first play though. I plan on doing the science play though on my 2ed run and on my 3rd I am thinking I will want to play as an evil character.
