As a lifelong gamer, my efforts on Wikipedia are largely devoted towards video games, with an emphasis on creating new, high-quality articles on obscure/quirky yet notable subjects that most people would not pick up on, such as little-known indie titles, niche games, game characters, levels and items. However, I do go outside the gaming sphere from time to time.
I also engage in behind the scenes activities such as suggesting page moves, discussing redirects, categorizing things, etc.
