My hobbies all go in phases I think. I stick with one mostly with the other hobbies just popping up occasionally.

Right now it's gaming and buying games/systems/etc, but I'm feeling like that phase is nearing it's end. After I play through FFV I'm probably done with doing a lot of gaming for a bit.

My next hobby that's slowly taking more and more time is reading.

Other hobbies include: writing, playing guitar, singing, acting, trying to teach myself to play piano, playing soccer (this I haven't done in a long time, but I've been feeling the itch lately), binge watching tv shows, collecting and watching horror movies, board games, running/going on walks, cooking, drawing, photography, hiking, geocaching, listening to podcasts...

I'm sure there are some others, but these are probably the most likely candidates to end back up as an obsession.
