People like having bigger numbers? They like the feel of their PC being more powerful/competent?Okay. Why would someone play for advancement vs not?
The desire to advance one's PC is fairly widespread among RPGers.
BW doesn't use random PC gen. It's a type of intricate, multi-faceted points-buy, filtered through a lifepath system. So I could have built The Fisherman differently. I could have chosen a different second lifepath, which would have allowed choosing different skills, or perhaps more resource points. Or even on the current lifepaths, I could have chosen Fishing B4 and Mending B2, instead of B3 in each; then the character would be better at fishing, but not as good at mending.I'm asking whether you can even evaluate whether one will generally be more successful at whatever challenges the game puts in your way. My impression is that the answer is most likely no.
1. The challenges change depending on your character goals/beliefs which makes things rather difficult to evaluate.
2. Even if you made a character with the same goals/beliefs/connections/etc presumably you could customize some other aspects of said character. Would any of those other aspects lead to having greater success at obtaining their goals?
The general idea is to build towards the particular vision you have of the character - who they are, what they've done, what they can do. Being familiar with the lifepath options, and the range of skills and traits, helps with this.
