I was thinking recently about how Wealth (Lifestyle, Posessions and Cash) are represented in non-espionage games.
Eg in Post-Apocalyptic games, I guess money becomes useless and is replaced by bartering for goods, so the Cash component of Wealth would probably stay at the default of 1.
PCs might allocate points to the Lifestyle component to get tricked out cars with armor, ram plates etc as in Max Max. They probably wouldn't own a house as PA heroes tend to roam about.
They'd also put points into Possessions to get lots of weapons (guns, chainsaws etc) and to provide goods salvaged from ruins.
How have you guys covered Wealth in your non-espionage games
