They really arent rare though. Nintendo has like hundreds of games that are game trials And only for nintendo switch online subs. Square we all have seen does a ton of these demo—> progress carries over. And Nintendo has been doing it now as well so i see more than this will just be more common place Overall Just see more and more game trials happening
Yeah, I like Square's save data carryover demo policy a lot, it's been great at selling me on games. But I love not having to pay for a game unless I know I want it.
