Transmission System Operator 2013
I thought it might be fun operating electric power grids, so I made it a game.
There’s a demonstration video here: https://www.youtube.com/watch?v=D1D7k9OCFn0
You can download the game (it’s totally free of course) here:

It’s still in alpha. I’d be happy to get some feedback. And bug reports :D.

I’ve heard great things about LD and I am definitely gonna participate in the next one.

There are so many different types of games and game makers you will certainly find people who will like (and give feedback on) games like this.
