complexity is a term most people struggle with.
i personally dont think most editions of DnD are very complex.
They are bloated.
Trap options arent complexity, tons of different (trap) options arent complexity.
having many stats to invest in isnt complexity if most of those stats are basically irrelevant for the class you play.
Sorry, I am not a native english speaker.
What would be a better term?
The existence of trap choices is bad, I guess.
Lets say a game has 100 options to build a char and 90 of them are bad.
An expert will ignore 90% of the stuff the game offers and he will feel great when doing crazy stuff with his OP char.
New players cannot see what is a trap choice, so they will consider most choices as being equal and they will probably end up with a bad char which will ruin their fun.
Kingmaker was my first pathfinder game and I made a bad char even though I did lots of reading about the rules before.
The game has so many classes, races, feats, skills and so on that its very easy to get lost even if you have played other RPGs before.
I am a bit scared because the new pathfinder game will have even more classes, races and so on plus your chars will become mystic.
At least in BG1+2 reading the manual was enough for me to understand the basics and make a useful char (after endless rerolling).
