Playing the Legend of Zelda: A Link to the Past (SNES) on my MiyooMini whilst my wife surfs - a great way to spend an evening!
Oh man, I forgot that even existed! I used an app for it for quite a while, I didn't realise how long it must have been since I used it
For me, it's using emulation. I'm currently playing Paper Mario: The Thousand Year Door from the GameCube, and there are very few android games that can match the quality of older AAA titles.
Plus, no microtransactions!
There's also the concept of informed risk, which realtes to informed consent, and this can be a big issue.
For example, if I ask a friend to come for a drive with me, they'll likely say "yes" on the assumption that the car is road safe and I have passed my driving test. But if I wait until we're already on the road to tell them that the fuel line sprays petrol into the footwell and the engine constantly misfires, then they agreed without understanding the full risks, and might have decided differently if they had all the info ahead of time.
I think any "reasonable person" would refuse to enter that sub if they were given a full understanding of the risks posed, and their likelihood.
Wherever possible buy outright, it is always cheaper. If needed, get a 0% interest credit card and use that to buy it outright. Do not fall into their trap of paying hundreds more for convenience and interest, all while never actually owning the device.
