What are old games you can 100% say stood the test of time and someone who's only played modern games would still really enjoy?
Games from from PS1 era and back. Console, handheld, PC, doesn't matter.
For me I'd say Super Metroid and Link to the Past, both of these games I played for the first time I think 20 years after their release and the lack of QoL features from older games just weren't a problem at all with these two.
Also I suppose a lot of Squaresoft RPGs from the PS1 era, but I'm not sure if they have truly aged well or if I'm biased from having played a lot of them back in the day. That said maybe Capcom's Breath of Fire IV would be one that actually stood well the test of time.
This post is a stealthy recommendation request for some older titles for me to go back to. Mind I was playing most of the games from back then as they were released but I suppose I missed a few gems specially in Nintendo handhelds.
