I have a decently powerful system that can probably run any game (though not at max settings for the most intensive ones that require like an RTX or something).
So games do I play to test the limits of my machine?
Windows 3.1/95 Edutainment titles.

But honestly, it's around time to move on at this point. It's been dormant for over a decade and there simply hasn't been enough interest for a revival of the series; in addition, Shining Force, another JRPG they worked on, hasn't seen an entry since 1998, which is even more dormant than Golden Sun. It's like expecting SEGA to make another Dynamite Headdy game at this point and it's simply not realistic expectations. I wouldn't get angry if the next game Camelot announced was a Shining Force sequel, or a Golden Sun sequel, or even a new JRPG altogether, but that's setting yourself up for disappointment.
Their portfolio has been mostly corporate-mandated Mario sports games sure but that's mainly because it's their bread and butter and they make a good, tasty bread and butter if they are given the time and effort required, similar to how Nd Cube does primarily party games. Mario Tennis 64, Mario Golf 64, Mario Golf: Toadstool Tour and Mario Power Tennis are legit good, and there are hints of brilliance in even Mario Tennis Aces. I liked Mario Tennis Open. World Tour is a very good Mario Golf title. I think they poured a lot less effort in their games since World Tour though.
