Fuck it. Have some links, I'm not rewriting all this shit.
I will be playing Baldur's Gate II and the Expansion using the G3 Fixpack, parts of the G3 Tweakpack, if you want the specific components I'm using, I can list them.
I need one main character, so look through these...
Races and Stats
Classes and Kits
After looking through the Class Restrictions, choose a favored weapon(s) type as well:
Katanas (magical Katanas are rare, the game even warns you of this)
- Two-Handed Weapon Style - bonuses while using a two-hander (does not include ranged weapons)
Dual-Wield Style - bonuses while wielding two weapons
Sword and Shield Style - bonuse while using a weapon and a shield (Try not to choose Bows/Crossbows with this, since they're considered two-handed ranged weapons...)
Single-Weapon Style - bonuses while only using a one-handed weapon
As a side note, Baldur's Gate II is very magic heavy. Which means magic-users can become insanely powerful and there's going to be huge amounts of magical spells thrown around during the game. Not to say that fighters and the like are useless, they get quite awesome as well (Monks get insane saving throws, immunity to magic, and instant-death hand-to-hand attacks, for example).
Have at it.
