The new UI design is also not universally loved, there was definitely a lot of anger towards it when it first released for being too "iOS-like" or otherwise changing familiar UI constructs like the statusbar too drastically.

I use the stock OS on a Pixel phone but have LineageOS on a tablet, so I think I'll prefer having the same UX across both devices, but tbh it's not that big a deal.

Wake it up? You mean turn it on?

Yup, waking it from suspend.

I checked on my machine in detail, and was surprised to find that it's using suspend-to-idle/s2idle, not even deep sleep. Deep sleep should save even more battery life, at the expense of requiring a couple extra seconds to wake from suspend (and at least on my Framework 12, requiring pressing the power button to wake rather than just opening the screen and/or pressing any keys)

cat /sys/power/mem_sleep should show you what your machine supports, and you can e.g. echo "deep" > /sys/power/mem_sleep as root to change this. I've tested both on my Framework 12 running Silverblue 43 and they both seem to function fine, though I'll leave my machine in s2idle as I'm not in particular need of maximizing my battery life (this laptop for me is currently homebound so battery life isn't the highest priority).

Same, I'm on Fedora Silverblue (which should be much more similar to Bazzite) on my Framework 12 and haven't experienced this. I regularly leave my laptop lying around off the charger for 3-4 days (will maybe wake it up for 10-15 minutes at a time every so often during) and it'll still be running.

The story demo was tiny compared to previous similar demos (Sky 1st, Ys X, DB 1), but given just how generous those previous demos were, and how this game isn't really the opener for this arc, just showing off a tiny bit of gameplay + enough story to situate the game is likely fine.

I'm on a bit of a Dragon Quest kick right now so I wouldn't mind, but VII seems like the absolute strangest choice to remake. It wasn't that long ago that the 3DS remake came out, which IMO was a fine remake all the way through (I'm ok with the shortened intro, having played through the first chunk of the PS1 original). I expect perhaps that version wouldn't hold up to modern scrutiny even on Switch/Steam Deck-style handhelds, but it feels like the effort would be better spent on getting a game like VIII which did feel compromised a slight bit in its 3DS iteration, or IX which has never seen a rerelease since the DS, a more proper remake?

VII is notably the only current missing game from the pre-IX offerings on mobile. I don't personally care for playing these games on mobile devices but I don't know how much of an impact that market has.
