- BG3 is not dark sun or Gothic.
I do not know dark sun, but Gothic 1 is set in a prison with hundrets of prisoners and only 13 of them are mages.
In the baldurs gate setting magic is allowed and it is something normal.
People using magic to fly or to cummunicate telepathically is as normal as we travel with a plane or talking through a mobile phone.
Unless you use magic to attack people or their property or you summon undead or demons in the middle of a town, nobody cares what magic you do.
Being a wizard is a normal job.
- In the real world people make a lot of things in order to get more power.
So it makes sense if characters in a fantasy world make choices that make them more powerful.
Training for another class to become profient with some skill or equipment or learning an ability that works good in combination with what you already have, sure why not.
Especially evil chars would do anything to increase their power, no matter what other people think about it.
This way you could also argue that min maxing is normal and you need a good role playing reason to restrict yourself from doing stuff that is posible.
- The IE games were very good, but a lot of things made little sense to me.
+ arbitrary restrictions, like only humans could be paladins or monks and only half elfs could be ranger/cleric
+ very unintuitive system. Some numbers are good when they go up (e.g. stats) other are good when they go down (thaco, AC, saves). Only extremely high or low stat values had an effect, no changes in a wide range. Only some classes could have a strengh between 18 and 19. Spells did not depend on anything but level, for many spells it makes no difference if they were cast by a lv1 wizard or a lv20 wizard with 25 int. Most classes could dumb 2 or 3 stats without any downside.
3E was more intuitive (higher numbers are always better) and you had more freedom, but creating a good char sometimes became complicated like rocket science.
In PK ( I consider Pathfinder as DnD 3.75 ) you had to look for every buff if it is a morale, luck, enhencemant or whatever bonus or if the AC is dodge, natural or deflection.
I know nothing about 4E and I have not played a 5E game so far, but from what I read I like the changes. You still have tons of options but they have simplyfied the rules. Now you have only (dis) advantage or not, there is only one AC and so on.
