To avoid exploits gamesas can implement a way to stop them :
I All players who die from a bountyhunting quest to have his stats lowered with 5 % -15% for 5-10 hours and i think you wont give your 10% of your stats 10 hours for some money.
II All players who die from a bountyhunting quest will have an impact on your aligniament and for like 3-5 hours to not be able to enter in cityes and bank your goods.So if u are a victim of a bounty all guards from the big towns will atack you on site 5 hours lets say.
III All players who die from a bountyhunting quest will give a good aligniament points to other players for 3-5 hours and they will kinda be more constant targets for anyone.So any player will try to avaoid to be a bountyhunter victim.
IV All players who are victims to a bountyhunter quest have a 25% chance to lose some of they items for 3-5 hours even if the items/gear are already saved.(3-5 played time hours usually to avoid loging out and just wait for the time to pass)
+On the other hand some reaward system can be implement even for the criminals after the time of hounting is elapsed (lets say 10 hours ingame time) and the outlow escape the punishment ,he can have some kind of reward or aligniament increased and the bounty hunter that fail to kill him may have got some penalityes or loss after his failure.
All these things can stop people to sell themself and die from a bountyhunter and in the same time some may avoid doing bad things in order to not be on any bounterhunter list ,but some may chose the path of the criminals and outlow if they are good enough to escape the bountyhunters becouse even themself can end with a reward if they are good enough.gamesas need to chose from these or even implement more ways to stop people from exploiting the bountyhunting system and some ways to make people chose this kind of dangerous path,altho it will not be a simple busines.
PS: I have trust that gamesas can implement a strong bountyhunting system and be a big plus in the harsh wasteland of fallout becouse bountyhunting can become a viable profession/sport/way of playng the game and were other games failed fallout can succeed.
I am the Formless in all forms.Strenght si the only measure ,all things can be resolved with violence and blood share.
