I don’t see any mention of the Civilization games. Civ III is my personal favorite but Civ V was also good. Keyboard shortcuts are a little bit quicker of course but it’s turn based so there’s no rush!

A lot of RTS games play fine with just the mouse, especially in the early stages of playing. I’ve seen a few mentioned but I’ll put Stronghold Crusader onto the recommendation list. I generally play it without any keyboard inputs.
