My idea to players can be idolized just for be protected in desert, or just dont get shoot from guard, and also to trade, not for abusing player killing, including players with 1+k reputation.
As far as i know - price for sell / buy raising dropping in good amount after investements in reputation.
for example i can sell some stuff not for 19800, with 0 rep but for 23500 with 700 or 900+ and even more caps with 1+k rep, wonder what price with 1.5k +.
also rep gained by trading is abit too low, after i sell stuff for 120k and didnt got items for like 200-1500 caps per 1 time, i got +30 or abit more rep.
actually after i sold stuff for about 1million to gun runners i raised rep from 600 to 900 rep cap.
and for do not be killed in town by idolized person just remove feature to kill with no shoot from guard in town.
