Clan_Lunaire: Ok thx guys. I"m not sure what min-maxing is though. Is it like powergaming ?
min-maxing in the Fallout games would entail only having the bare minimum skillpoints needed to pass some important tests throughout the game, having a very specific set of character attributes during character creation with a plan on exactly how the character will look after having acquired all possible attribute upgrades later in the story. It often means having no Endurance and no Charisma because in a perfect playthrough you never take damage (and reload a save if you do), and Charisma doesn't actually have any meaningful bonuses to a perfectly built solo character.
With all the attributes and skill points saved, you can then max out certain other attributes and skill points to make a character with maximum efficiency and minimal investment to accomplish every task the player intends to undertake. The ultimate Fallout character is someone with high enough speech skill to pass every important speech check, just enough lockpicking to pick every important door and lock, and maxed out combat skills with precisely the small set of weapons the player intend to use. This often means he will be shooting at max distance and never take any damage.
I personally hate this mindset and will without hesitation play "bad" premade characters in games like Fallout and Arcanum. One of my favourite Fallout character concepts is a drug addicted janitor (repair and lockpick) who is bit of an amateur boxer. Yeah, lots of wasted skill tags and traits, but it makes the journey much more enjoyable when there is a story behind every decision.
