I just think that playing a game like Skyrim or WoW, you get satisfaction from completing quests/leveling up etc... would it not be better to go rock climbing or cycling and get satisfaction from that instead. The satisfaction from building something yourself e.g. a computer is a lot more self-gratifying that just going into a shop and buying one isn't it?
I'm not sure we're allowed to go chopping people up with swords and fight dragons in real life.
