I definitely don't hoard much. Especially since you can just download anything again when needed.
I have a friend who keeps a stash of downloaded movies thats several TBs big. Never understood that.
But making a choice seems to be difficult for me. How does one develop their taste. I feel like after playing all these games and watching al these movies, i still feel interested in everything. And I'm unable to tell based on just the cover or a review whether I would like it or not.
For movies I actually don't like looking at reviews or trailers at all because they often show too much already.
