I adore the first game. Played the hell out of it when it came out, bought it at some point when it got ported to PS4, loved it. Didn't beat the super long end-game dungeon, and I don't think it's very well balanced in the sense that not every character feels as good to play as the others, but it's still a great game. Probably my introduction to roguelike elements in maps, unless the bonus dungeon in Lufia II counts.
I haven't played a whole lot of the second game, although I liked what I played. Got it several years after release on PS2, put in a handful of hours and then got distracted by something else. Same thing with the PS4 rerelease. I owe it another chance, there's just too many things on the backlog at the moment.
I think the series is ripe for another entry, I'd love to see what they could do with the Georama system with better technology. I don't think it'd need to be anything crazy, just made a good-looking lower-budget game that could run on PS4 or PS5. Kind of like they did with the MediEvil remake several years ago. I'd love to see it elsewhere but I believe Sony owns the rights so the odds are slim.
