A lot of people complain they don't get enough gold from their adventure, but what is not enough gold to one person maybe too much gold for another. From the standpoint of someone running the game, you might not really care, and just throw gold at the party, while another DM might just hold off on gold, giving it out sparingly.
Of those two methods, I tend to lean towards sparingly because I feel that if you flood players with gold here and there, that it will not feel "great" or "special" as a reward when they kill a big bad. Who really wants to find tons of gold everywhere, only to finish a long cave adventure only to find the same amount of gold you've been finding all along?
Characters finding gold should be something big, or major. Sure a few pieces of gold on the leader of say a bandit patrol that attacked the party would be acceptable, but to find gold on every bandit, and their entire coin bag filled with it? No I don't think so.
You want your players eyes opening up as you describe what their character sees when it comes to massive amounts of gold they found.
I was in a group a while back, where the DM gave gold out like it was candy, everywhere and every monster had gold, nothing but gold. After a while, it became like finding copper for the party. When we finally reached the end of the quest, and returned the item we quested for, we were rewarded with... Gold.
It was like, "Yawn, just throw the gold on the pile and we will worry about what to do with it later" attitude with the party.
One of the players in the group actually decided to bring his laptop and design some type of accounting software to deal with the gold, and who had what.
What do you do in your games, or how do you feel about giving out gold?
