No one answered this question before when I asked it. So I am going to ask because no one in the last 14 pages has directly or indirectly answered it. Why is exp for killing monsters the only motive for doing it. Is it because no game has given you meaning ful rewards otherwise.
Example lets say your adventuring and you find a cave. Going through the cave you fight a bunch of monsters a big bad voodoo daddy and find a chest. Inside the chest are lute strings, and a note saying dear big bad voodoo daddy here are your magic strings. You turn to your useless bard and say hey you have a pretty high lore skill identify these and put these on you lute. boom 10k exp and now your bard isn't useless he's playing songs that fear enemies charm pretty ladies at the inn even getting sirens to fight with you.
Now knowing about this cave not giving you exp to fight the monsters would you roll a complete part of stealth just to get threw this one part even if you arnt a sneaky kind of player.
Sorry for punctuation doing this on my phone.
