I think gaming is a fantastic medium for a seemingly subconscious, even subliminal learning - you can have fun and be virtually unaware that as you're having fun, your brain is absorbing a great deal of knowledge or gaining new perspectives depending on the actual research and groundwork the game designers have put into the game and writing and design implemented.
Games are also inspiring in their own right - depending on the character interactions, nature, morality, ethics, and whatever choices presented with. I can come up with a range of examples, and some of them far less literal than "Games taught me how to shoot a gun, hur hur".
StarControl 2: actually helped me ace primary school astronomy science. But apart from that- the heavily text-based format of the game (all dialogue was in text) - taught me a lot of English. Presented in creatively written context and humor, the rather complex English use in the game articulated into my current level of English. That being said, English is my second language - the sheer number of well-written English games I played growing up had my fluency and proficiency of English far exceed my Chinese proficiency. The great writing in the game also taught me varying types of humor, charm, and options and opportunity in diplomacy and social interaction. I am by nature a very diplomatic person- I feel in some way I owe a bit of it to games like this.
Most old Point and click adventure games: Resourcefulness; you'd never think games could teach you too many actual practical life-skills, but point and click adventure games encourage lateral thinking and in some ways, cunning and perceptiveness to our environments. I have had moments in my life- I'd improvised tools to accomplish a particular task, observe and rationalise to more rapidly gain proficiency in something that otherwise needed to be taught/coached intensively. In general, I always feel that something could always be done differently if not in better ways because of the open options I feel that objects and my surroundings could be used.
RPG/Adventure games - anything with a deep enough story: I think having played a lot of those as a kid, I learned a lot about virtue. It gave me perspectives on what should be important in life, and that performing good actions can be a good unto its own regardless what you gain or even lose to perform such an action. Heartwarming moments in a story-driven games can inspire us to think what difference we can make perhaps even in the real world, and if we truly relate to those moments, we often more consciously seek to create these wonderful moments ourselves in our real lives. I can say on many occasions, summoning the courage or will to do some things for some people in my life and even strangers have earned me warm, fantastic and proud memories that will last me for life: standing up for someone you care about or defending/aiding the someone in need, doing something extravagant and sweet for a loved one, taking decisive action in a crisis, and generally doing anything that makes you remembered for the things you do. These are powerful moments.
Games in general can open our imaginations as the creators of the game confer their creativity and ingenuity upon us by letting us experience their work.
I could go on, but this would go on too long - I listed what I think the more important things games could teach us. Of course- I am not saying I owe ALL my virtues, resourcefulness, skills, character and courage to games - but in some ways, they encourage and inspire us in the way they simulate the situations we could be in and how we could behave and interact if we were in them. I have a 'take-what-you-will' approach to various media and life in general, I learn what I can and find whatever is valuable and know that it will be put to use; it is possible to experience these and learn nothing with a closed attitude towards them, but I hope this attitude will change in most people, because I find a lot of good games actually teach truly valuable things to people than just "I learned how to shoot a gun" or "Stronger is better" - if people took their focus away from the 'how' and paid more attention to 'why?', i.e: as opposed to "I learned how to shoot a gun" have we ever thought "why am I shooting this gun? do I believe in this cause?" and from "I trained hard to be strong" to "where can I use my strengths so I can do something that truly matters with it?".
Okay, /philosophical rant about games.
