Well my original plan was to make Steam Big Picture Mode as my main shell to navigate my computer and make explorer a shortcut when I want access Windows (along with Origin for some EA titles). I have been very contempt with my setup, but then MS put AAA titles in the Windows Store and some are exclusives (ReCore). I tried to link the Windows Store app into Steam, but Windows forbids access to the Windows Apps folder (understandable). Now I have to turn on explorer navigate with a mouse and keyboard to the Windows Store to get games that way which is cumbersome cause I like Steam Big Picture Mode and just having to use a controller.
Then I discovered Toyota###'s Durango skin for Kodi which mimics a console (specifically Xbox) environment through Kodi. He also has one for PS4 for those Sony fans. The problem I have with Kodi are certain add-ons which hackers can gain access through "man-in-the-middle" ways. I plan to use no such add-ons (even if every freaking tech nerd keeps recommending them), but I'm afraid they're included in the skin I want to use.
I've been looking into Plex, and I love the aspect of being able to watch a show and continue watching it from any Plex app on any device (it also has a Windows Mobile app). I'm just leery over having to pay a subscription for certain features, but I guess paying for great features is better than risking exposing personal info to hackers.
