With my reflexes (part AS, part sheer age) I like very few computer games, as most of them require some speed of reaction.
"Real-time strategy games" are a particular annoyance.
I have to go back to quite old-fashioned ones (I may soon need a special obsolete computer to keep them on) to find what I'm really looking for.
Combat Mission: Beyond Overlord was excellent.
Earlier: Empire; the original Civilsation; Railroad Tycoon...
