Zero interest in gambling and not really all that interested in shows; they're super expensive.
After writing the post and getting so many great suggestions I started really thinking about what I love doing. That thought and investigation led me to a PC based game called Cities: Skyline.
It's an incredibly complex simulation game where you start with a piece of land that has water on it, a budget of $70k and one highway.
From there you build your "city". You have to bring in water, electricity, sewage, industry, residential... everything a real city needs. But what they've left out is the pesky people. In SIM City it's more of a reality game with people. Cities is completely different. There are no people that you have to 'build' it's just the city planning and development side of it. And since it's a PC game are no "in game" purchases that are so annoying with most iPad games.
I started last Thursday and haven't slept much since. My city is called "Springdale" and I have 38,000 citizens and the city has a budget surplus of $3.9 million!
I haven't had this much fun in a very long time. The game pushes every one of my buttons. It's complex so satisfies my learning, it's single player (I don't like multi-player games), I can 'pause' my city so if I choose to do something else for a week my city doesn't burn down (constant care and feeding of a game is a nuisance), and there is a community of ardent players to interact with.
Bottom line - I've found something to do that I enjoy, is free after the one-time purchase of the game at $40, and it highly stimulates my brain. Retirement is awesome again cause I sure couldn't do this while working!
