I’d recommend ignoring all these suggestions and trying some out for yourself.

You should be able to return the ones that don’t work for free within 30 days.

It’s absolutely done, but most players need something new sold to them in order for them to play it.

They could just replay the old ones, but they won’t even if it’s the same experience.

Maybe if there was a remaster of the old ones, that would get them to spend money and play them.
