What kind of mini games would make this game more interesting to you?

I think this is a question for the tappers who have been at it fairly long. It's still relatively new to me at 7 months and everything is still pretty fun - some events more than others (not talking about Easter LOL). The developers are trying to please beginners (or at least those at level 20+/-) and people with bazillions of dollars. Not too easy...

I will be interested to see what the mature tappers have to say.
