I just bought Fallout: New Vegas, but I'm having some issues starting the gameplay. I am not a very experienced RPG player in general and the only game from the Fallout series I've played so far was Fallout: Tactics. Some of the questions may be on the "duh" side of things, so please be patient.
Anyway, my questions:
1) After you've used a weapon, how do you holster it so that you don't wander around in a fighting stance?
2) Some of the weapons' description at the Fallout wiki says that they can be concealed, either with Sneak above a certain value or regardless. How does one conceal a weapon, and how helpful is this ability in practical terms?
3) How important is Charisma? If I lower it in order to boost other stats, am I setting myself up for trouble later in the game?
Thanks in advance
