I never put much stock into Microsoft Store apps, but I do have a newfound appreciation using them with the Ally. Even for stuff like the streaming apps, the touch optimised menus just make for a good experience.
Your shelf is pretty nice! I wish I could buy figures as well but dust allergy would be hell for me. That's all I have, games-wise. I have some other controllers but they're in storage box. Once I'm done moving I think I'll buy a better bookshelf than this one. There's also another one with all the consoles I have except some.
