When I played 3e we were swimming in gold.

Slowed-down level advancement and 1e modules = very wealthy characters.
Not that I-as-player minded.

It gave the DM headaches, thoguh.
Sure you do. Just pay someone that 100K to drop a Wish and then start hauling in the furniture.
More seriously, all of that sort of thing is what I'd want my PC to be doing after retirement from adventuring so he could oversee the process and be involved in it day-to-day. But I'd want to be saving up for it all the way along, such that when I do retire I've enough cash on hand to afford the clearing, construction, etc.
But if saving up for it means I'll never get enough xp to get to that level...it just doesn't make sense somehow.
