Sweet, have fun playing around when you get it!
On build quality, my set's pretty good, but I did have to squeeze the upper right side of the deck to snap the case shut, which wasn't closed fully at the factory. Didn't affect anything, but it's no Vita/Switch build quality.
Ubi/Epic update, after dropping into Desktop Mode I can get "offline" Ubisoft saved games uploaded to their cloud service, if I'm tethered to my phone. I'm not able to actually do full Offline launching the game yet. I configured Epic to save my credentials locally, which does let me login when disconnected, but only to Epic. The Ubisoft games inside Epic have ties to the Ubi Connect app, and won't launch if they don't have some type of internet connection. No plane trips for that one, but I should be able to play it in different rooms of my house and sync up, with some manual effort. It forces me to enter in my Ubi credentials every time it gets disconnected, including MFA, which is annoying when my password's a 16 character random string and I have to use the software keyboard.
