Good luck! That extra money and space will come in handy. Less buyer's remorse is also good.
Made a similar decision a few weeks ago. But I'll still be collecting a few bits on special occasions. Some collectibles are pretty close to art (ex: lithos, artbooks, statues, etc) and bring what we see in the game world to the real world. Some of them may also serve as reminders of what we love in our favorite games.
But yeah... I'm ignoring most, if not all, CEs. Kinda ironic since this community is dedicated to CEs. But a lot of them, these days, just aren't worth our time or money. Eventually I just forget about most of them.
I really hope more folks feel galvanized and follow your example. You've certainly helped me cause I feel I made the right choice. I feel free!
