Honestly, I really liked Zork. (I was the right age when it came out.). Never been as captivated by a game. More in the imagination than in the graphics.

I’ll put Civilization V (and sometimes IV) in second place. Homeworld was great too.

My wife and I use Our Groceries.

You are correct, but I find dialing an easy-on-the-eyes colour and a good font reduces eye strain. It lets me keep the font size small with less fatigue especially as my eyes (and I) age.

As for what theme? Usually it’s as simple as browsing through the presets until one jumps out. Takes a few seconds. Having more presets adds about 2 seconds to the process and often (not always!) results in an even better choice. Have no idea the name of the theme I end up with.

Besides, tweaking this can be fun if you’re between thoughts - you end up learning the inner workings of the environment.

They really look nice. A good font makes a huge difference.
