Few things that are missing, I think:
1. the ability to sell old stuff
2. the possibility to hire more painters
3. more stuff to buy would be nice, too :)
But I think that the game is fun that far. Just makes me a little sad that it's very hard to buy anything at all, because the expenses raise like every year, eventhough I don't really get why... I also couldn't really figure out what fame was good for.
