Here's my idea for the day:

Cafe World takes way too long to play. I've got like 30 stoves now, and that's a lot of clicking and messing around just to play a game. They always have incentives and special game features, which invariably involve going through a bunch of tasks to get some nominally useful new thing.

What about doing something useful? Cafe World takes too long to play. I have to click 15 stoves 4 times each to make a batch of something. They have these "Super Stoves" where I can one-click them and it automatically makes for dishes. How about you make a game feature that I can do a quest and the result is, I can combine my regular stoves into a Super Stove and save myself a haystack worth of effort.
