I think the most I ever got in a playthrough was 22-23k. Gold doesn’t really matter if you make a habit of stealing it back from vendors after you make purchases.
This is ultimately why I started the post. I was curious about the games economics and the potential breaking of it due to this. I suspect when we get to larger cities it may be harder to steal it back, due to more population there and the increased reliance on invisibility, but the issue is that we can just load/save. I'd very much like to have the gold mean more in the current game play, so iv been testing concepts with it to figure out what items are needed and not and how to optimize income. I was curious how high others got so i can measure how evil i was being with the load/save features. This seems to be a big motivator to playing online.
