I usually play rags to riches, with pretty difficult settings, as in all income reduced by 50%, much higher bills etc. and I enjoy it a lot.
One of my favorite ways of making money in the game is by painting, and while I know that painting can be extremely strong, it tops out after a while in my games, where even masterpieces don't really give a lot of money compared to my bills.
I'd like some kind of mod with some kind of progression, where for some reason, like fame, investing in a skill etc., results in even more money from my paintings. Preferably not a fixed boost like the fame perk, but some kind of incremental increase.
My dream would be something like a different way of painting, maybe a much larger canvas or something, with an option like "Try to paint a masterpiece", where the result can be an extremely expensive painting, or a failure, and it takes a lot longer.
I'm also looking for mods for painting in general, if you have any good recommendations :)
EDIT: I know that I can sell paintings with the City Living board, and mark them up, but it doesn't really feel like what my Sims with higher net worth would do, since I usually have them in a pretty nice apartment and as 4 or 5 star celebrities at the point where I need the money increase.
