I have created a new site called Pretirely. It's a "Choose Your Own Adventure" type game where you try to make your assets last through retirement. As you navigate through the years, you'll encounter an economy that looks just like some year in the past, and you'll see your assets affected by inflation, high and low stock and bond returns, and changing home values.
This is the beta version of the game. You get a random starting point and can cycle through the years to see how it turns out. You can click on the "Options" button in the top right corner to completely start over with a new scenario, replay the same values a second time to see if it turns out differently or set your own starting values.
I'm working on many improvements to this game, like adding the ability to stop and make decisions and changes as you step through the years, throwing in random events you can't control, and showing the effect of income taxes and minimum required distributions.
This game is just that, a game. It's in no way a predictor of the future. But I think it's interesting, and hopefully a little educational, to try to "live" through a variety of situations. I hope you'll keep checking back and let others know about Pretirely!
