I've never been much of a gamer, nor much of a student for very much the same reason: There are too many neat things that are real. But I recognize that simulation/training programs and games are really two faces on the same code. So.. I'll see what I can find, and in the process will probably end up with something I can use for my simulation/training.
(Actually, there is one computer game I have loved, but never gotten beyond: adventure. Also, I do love the board game Go, but have never gotten very good at it.) -ben
