What? This game gives you money like no tomorrow! I've got millions of gold and now don't bother to pick it up because I have so much
You're not playing the game correctly if you can't kill a few mobs and get some gold!! Find some people with a '?' above them and they'll usually give you a quest to complete, after I did a few quests and upgrading my armour/weapons from the mobs I killed, I was starting to get quite a bit of gold
Going back into the same caves resets the mobs (can't remember if chests are reset?) so you can keep killing them and gaining more gold!
There are also some items that increase the chances of finding gold!
You don't need to run two copies, believe me!!
